FPGA vs. Microcontroller: Battle of Embedded Systems

Introduction to FPGA vs. Microcontroller:

A wide range of electronic components are used by designers to create functioning embedded systems. These consist of peripheral devices, memory, and CPUs.

The intended objective use of the system determines its level of complexity. One of the trickiest and most involved decisions is selecting a processor because it will have an impact on the system’s computing capacity as well as how well peripherals and other parts are managed.

Using a Field programmable gate array (FPGA) or microcontroller is the most popular choice for the designer.

Discovering the exciting worlds of microcontrollers and FPGAs (Field-Programmable Gate Array) illustrates that these two technologies are essential to embedded systems and digital design.

By programming them at the hardware level, FPGAs are incredibly flexible integrated circuits that enable users to design Versatile digital circuits. 

Their great versatility makes them perfect for intricate applications that need quick prototyping and reconfigurability.

Conversely, microcontrollers are small integrated circuits that house a memory module, a processing core, and several peripherals on a single chip.

They offer an affordable alternative for simple to moderately complicated applications because they are made for certain tasks.

A comparison of FPGA Vs. Microcontroller is given in this article. To compare FPGA and Microcontroller, we examined their distinctions and similarities in architecture, use cases, benefits, programming and configuration, and other areas.

Understanding of FPGAs

What is FPGA

Field-Programmable Gate Array, or FPGA for short, is a class of integrated circuits. After it is manufactured, an engineer or designer can Configure it to perform several functions.

ASIC chip technology is directly competing with Field Programmable Gate Array, or FPGA, technology. Fundamentally, FPGA is a semiconductor that can be Reconfigured and altered to do different tasks at any given time.

It is made up of a variety of Configurable interconnects and Configurable Logic Blocks (CLBs) that can be set up to create Versatile digital circuits.

By changing its internal connections and logic, FPGAs may be Reconfigured to do multiple jobs, unlike microcontrollers that have set hardware and execute instructions sequentially.

Logic elements (LEs) and programmable interconnects are the two primary parts of an FPGA. Digital circuits are constructed from logic elements, which are capable of carrying out a wide range of tasks like memory storage, arithmetic, and simple logic operations. 

A flip-flop, a look-up table (LUT), and other parts that let it execute complicated operations are usually present in any LE.

On the other side, programmable interconnects oversee the joining of the LEs to create the required circuit. They provide enormous versatility in the construction of custom digital circuits since they may be set up to make a wide variety of connections.

FPGA Architecture

FPGAs offer programmable fabric, DSP slices, block RAMs, and PCI Express compatibility as examples of their heterogeneous computation platforms. Because these compute resources can all be used simultaneously, they enable pipelining and parallelism of applications throughout the platform.

Logic units, memory, and programmable interconnects are the essential parts of an FPGA. Each maker uniquely arranges these blocks.

Flash EPROM, anti-fuses, and static RAM (SRAM) are the three types of FPGAs. Each programming element in SRAM programming uses a little static RAM bit. A switch is turned on when writing the bit with a one, and off when writing with a zero.

An anti-fuse, which is made up of a tiny structure and typically doesn’t form a connection like a standard fuse, is another technique. The two sides of the anti-fuse join when the device is being programmed with a high current. A third, more recent approach makes use of flash EPROM bits for every programming component.

Based on the configuration of its internal blocks, FPGAs can be divided into three groups:

Symmetrical arrays

The rows and columns of a matrix hold the logic components, sometimes referred to as CLBs, which are connected. I/O blocks encircling this symmetric matrix connect it to the outside world. An n-input Lookup table and two programmable flip-flops make up each CLB.

Tristate control and output transition speed are two other features that I/O blocks control. Interconnects are used to construct routing paths.

The latency of direct interconnects between neighboring logic parts is less than that of general-purpose interconnects.

Row-based architecture

Programmable connection tracks and logic module rows alternate in a row-based system. Here are the input-output blocks located on the outer margins of the rows. Vertical interconnects allow for the connection of one row to neighboring rows.

Logic modules can be connected in a variety of ways. Combinatorial modules are made up entirely of combinational blocks. Flip-flop and combinational functions are included with sequential modules. You can construct intricate combinatorial-sequential functions with this sequential module. Anti-fuse components link the smaller sections of the routing rails.

Hierarchical PLDs

Hierarchically arranged logic blocks and interconnects comprise the uppermost level of this design. Numerous logic modules exist in each logic block. Every logic module contains elements of both combinatorial and sequential functionality.

The programmed memory is in charge of all these functional parts. Programmable interconnect arrays facilitate communication between logic blocks. Surrounding this structure of logic blocks and interconnects are input-output utilized blocks.

FPGA Programming and Configuration

Programming and configuring FPGAs entails defining the device’s connections and logic to define the functioning of the FPGA. Usually, this method includes creating a configuration bitstream using Hardware Description Languages(HDLs)

Hardware Description Languages (HDLs):

• HDLs that are used to describe digital circuits embedded within FPGAs are Verilog and VHDL. 
• These programming languages enable designers to specify how the logic blocks and interconnects of the FPGA should behave by giving them a high-level, legible representation of the intended functionality. 
• HDLs make it possible to use a combination of dataflow, behavioral, and structural modeling techniques to describe complicated digital systems. 
• After the design is finished, the HDL code is synthesized into a lower-level representation that can be utilized for additional processing and optimization, like a gate-level netlist.

Bitstream Generation and Configuration: 

• After that, the synthesized design is converted into a binary file called a configuration bitstream, which holds the configuration information for the logic blocks, interconnects, and I/O blocks of the FPGA. 
• Place-and-route is the process of matching the logic components of the design to the physical resources of the FPGA and figuring out the interconnect routing paths. 
• Through an external memory device or a specific programming interface, the resultant bitstream is loaded into the FPGA’s configuration memory. There are two methods for programming an FPGA: one involves loading an MCS file directly from a FLASH device connected to the FPGA, while the other entails configuring the FPGA with a bitstream via the JTAG interface
• The FPGA’s internal connections and logic are set up by the defined design once the bitstream is loaded, allowing the device to carry out the intended tasks.

Configuration Memory: 

• The bitstream data that specifies an FPGA’s operation is kept in the configuration memory of the device. Usually, this memory is volatile, which means that when the device loses power, the data is gone. 
• Consequently, FPGAs need to have their configurations updated every time they are turned on, which can be done through a specialized programming interface or by loading the MCS from an external memory device. 
• Additionally, some FPGAs provide non-volatile configuration memory options that enable instant operation by retaining the bitstream data even in the event of a power outage.

Custom digital circuit implementation is made versatile and adaptive with FPGA. Without requiring actual hardware modifications, designers can specify the FPGA’s functionality and update or alter the device’s behavior as needed by using HDLs and configuration bitstreams. Iterative design, quick prototyping, fixing hardware issues, and deploying new features in the field are all made possible by this flexibility.

Advantages of FPGAs

Better Performance

One of the main advantages of FPGA is performance. FPGAs offer an advantage over CPUs since they can process data more quickly and process data in parallel, something that a traditional CPU cannot do. 

Carefully designed FPGAs can execute any function faster than a CPU executing a series of instructions from software. Additional gates and wiring enable FPGAs to be Reconfigurable and flexible. This costly overhead causes FPGAs to run more slowly than ASICs. 

Reconfigurability

Reconfigurability is the main advantage that FPGAs have over all other solutions. This suggests that even after a circuit has been created and put into operation, FPGAs can still be updated, altered, and modified to carry out completely different tasks from those for which they were originally intended.

The work and cost required to maintain these chips over time are reduced by their Reconfigurability. Rather than having to redesign or replace hardware as it matures, you can just update its code and program it in the field with the new capabilities.

Cost Efficiency

 Because FPGAs can be reprogrammed multiple times, even if their initial cost is higher, they are quite cost-effective over time. Without a doubt, one advantage of FPGA architecture is this. They save you from paying any ongoing costs associated with bugs that you may otherwise be required to pay if you decide to employ an ASIC. 

Apart from the fact that FPGAs don’t require expensive tools for design or configuration, ASICs have large upfront expenditures that are avoided when using FPGAs. ASICs also end up being more expensive in the long run since hardware redesigns are necessary whenever updates and enhancements are needed. 

Parallel Task Performance

In applications where timing is critical, sequential data processing processors are usually not used. Multiple blocks that process data simultaneously can be designed into FPGAs.

When compared to other processors like ASICs and MCUs, this suggests that it can offer significantly higher scalability and time-critical data processing.

Prototyping

One benefit of FPGAs is that, as was already said, they are reconfigurable and reusable. For prototyping, especially for ASIC validation, they are consequently the best choice. Before you tape out your ASIC design, it is imperative to make sure it is functional and serves its intended purpose. 

If your chip needs to be upgraded, you will need to invest a significant amount of time and money in redesigning the ASIC due to its high cost and difficulty of production. Because FPGAs are reprogrammable, you can experiment and find the ideal configuration on a single chip by modifying the configuration. 

Once prototyping is complete and the best course of action has been determined, it is easy to convert the FPGA into a permanent ASIC and put it to use.

Faster Time to Market

The ability to swiftly finish product development and shorten time to market is one of the main advantages of FPGAs. FPGA design tools are easy to use and have a little learning curve.

Moreover, FPGAs are designed using HDL, a higher description language that doubles as a modular programming code. Using HDL code, like that found in Verilog or VHDL, for design makes the process extremely efficient and fast.

It is relatively easy to test and validate the design in the lab by reconfiguring FPGAs. Quick change times allow bug fixes to be applied in short bursts.

Simpler Design Cycles

Design tools handle much of the work, including placement, routing, and timing about the specifications you’ve specified for it because FPGAs have easier design cycles than ASICs. 

That’s why they hardly ever require human assistance when converting the computer code into a downloadable design.

This streamlines and speeds up the entire design cycle. If the design does not operate as intended, a new downloadable code can be developed in a matter of hours.

Adaptability

Reconfigurable FPGAs spare you from having to rebuild the product each time an update is needed, enabling you to modify and adapt at the consumer level. 

The product is easily upgraded and customized to meet the demands of the customer even after it has been planned, built, and delivered.

Real-Time Application

As was already noted, FPGAs are perfect for time-sensitive systems because of their more efficient processing architecture.

They are ideal for real-time applications because they can process larger amounts of data more quickly than competing products.

System on Chip

From the 1990s onwards, FPGAs have more gates. This made it possible to add CPU cores, ranging from one to several, and unique hardware code inside the FPGA.

Because hardware design and CPU cores are integrated into a single chip, FPGAs function as a system on a chip.

Understanding of Microcontroller

What is Microcontroller

A microcontroller, also known as an MCU or Microcontroller Unit, is a single integrated circuit (IC) that is usually used for a given purpose and made to repeatedly carry out particular duties.

A microcontroller is akin to a system on a chip (SoC), albeit with less sophistication, according to current terminology.

A microcontroller is one of the components of a system on a chip (SoC), however, it is typically integrated with other sophisticated peripherals such as a graphics processing unit (GPU), a Wi-Fi module, or one or more coprocessors.

It has a processor, memory, and programmable I/O. In essence, a microcontroller receives input, processes it, and then, depending on the information it has received, produces a certain action.

Microcontroller Architecture

A microcontroller’s architecture is a key factor in defining its functionality, simplicity of use, and power consumption. The Central Processor Unit (CPU), memory, and peripherals are the main parts of a microcontroller’s architecture.

Central Processing Unit (CPU): The microcontroller’s central processing unit (CPU) is in charge of carrying out instructions that are kept in the program memory. It does data processing and manages the peripherals of the microcontroller. 

The performance and power efficiency of the CPU can be greatly influenced by its architecture (e.g., Harvard or von Neumann) and instruction set (e.g., RISC or CISC). Some popular CPU architectures for microcontrollers are AVR, PIC, and ARM Cortex.

Memory: A microcontroller’s memory is used to hold the data and program code needed for it to function. Program memory and data memory are the two primary categories of memory. Program memory is where the instructions that the CPU carries out are stored. 

It is commonly implemented as non-volatile flash memory. Data memory is used to store variables and temporary data used during program execution. It is often implemented as volatile SRAM. A microcontroller’s performance, power consumption, and suitability for a given application can all be influenced by the size and kind of memory it contains.

Peripherals: The peripherals are extra parts that are incorporated into the microcontroller and offer particular functions. These can contain timers, counters, Pulse Width Modulation (PWM) generators, digital-to-analog converters (DACs), analog-to-digital converters (ADCs), and communication interfaces (such as SPI, I2C, and UART). 

The microcontroller may interface with external devices and carry out a variety of functions thanks to peripherals, including reading sensor data, operating actuators, and corresponding with other system components.

The ease of use and appropriateness of a microcontroller for a given application can be greatly influenced by the peripherals’ availability and capabilities.

Microcontroller Programming and Configuration

To program a microcontroller, one must write code that defines the necessary functionality, compile it into machine-readable instructions, and upload it to the microcontroller’s memory. High-level programming languages, development environments, and tools are usually used in this process.

High-Level Programming Languages: Python, C++, and C are examples of high-level programming languages that are frequently used to program microcontrollers. These programming languages enable programmers to create code that is simpler to comprehend, maintain, and debug by providing a more legible representation of the intended functionality. 

In addition, libraries and frameworks for common tasks like communication protocols, sensor interfacing, and control algorithms are provided by high-level languages, making the development process easier.

Compiling and Uploading Code: Once written, the code needs to be compiled so that the CPU of the microcontroller can use it to perform machine-readable instructions. This procedure entails reducing the size and performance of the high-level code and converting it into a lower-level representation, like assembly language or machine code. 

Then, via a programming interface like a bootloader or an In-System Programming (ISP) connection, the compiled code is uploaded to the microcontroller’s program memory. Additionally, Over-the-Air (OTA) updates are supported by certain microcontrollers, enabling wireless code upgrades without a physical connection.

Development Tools and Environments: Specialized environments and tools are frequently needed for microcontroller programming and development to make the coding, debugging, and testing processes easier. Integrated development environments (IDEs), like Eclipse, Keil, or MPLAB X, are examples of these tools. 

They offer a centralized interface for creating, building, and debugging code. During development, debugging tools like emulators and in-circuit debuggers can also be used to test and troubleshoot the code. A microcontroller and a variety of peripherals are included in development boards and evaluation kits, which can be used to prototype and test the functioning of the code in an actual setting.

Advantages of Microcontroller

Compact and Portable: Microcontroller-based devices are very portable because they are usually small and light.

They are portable, so researchers can do on-site analysis and field study in various locations.

Particularly useful applications for this portability include remote research facilities, healthcare settings, and environmental monitoring.

Comparison of FPGA Vs. Microcontroller

Both FPGA Vs. Microcontroller are representations of hardware. They are made to serve the embedded system market, where hardware and software combine to make a design’s total functionality possible.

FPGA tasks require not only the fastest feasible solution time but also the least amount of power and resource consumption. However, microcontrollers are limited to a defined Instruction Set Architecture (ISA) and are unable to process data above a certain threshold because of their inherent hardware-fixed architectural nature.

The following are some points on which we can compare and contrast FPGA Vs. Microcontroller

Performance

In evaluating FPGA Vs. Microcontroller performance, it is crucial to consider the tasks each device intends to handle. Microcontrollers are designed for sequential processing; FPGAs, on the other hand, excel at parallel workloads.

The parallel architecture of FPGAs, which comprises several programmable logic blocks and interconnects, allows them to perform various operations at once.

Digital signal processing, image processing, and encryption are just a few of the applications where FPGAs’ great performance is made possible by their parallelism. Real-time processing of high-bandwidth signals or high-resolution photos is made possible by an FPGA’s ability to process many data streams in parallel.

However, microcontrollers are built for tasks involving sequential processing. A few examples of the things that affect their performance are the CPU’s clock speed, architecture, and instruction set.

Microcontrollers can still function well enough for many applications, especially those involving control systems, sensor interfaces, and communication protocols, even though they might not be able to match FPGA’s parallel processing capabilities. 

In some applications, the microcontroller’s simplicity of programming and lower power consumption might be helpful, and its performance is frequently enough to suit the needs of the system.

Power Consumption

FPGA is made to process large amounts of data quickly, have low latency, and handle large amounts of data. The engineers are challenged by the need to have all these features at a minimal power consumption. In an FPGA-based design, there is always a trade-off between functionality and power.

Furthermore, a significant amount of static power consumption is inherited by FPGA architecture due to underutilized logic (i.e., unused transistor) resources; occasionally, inadequate placement and routing also contribute to an increase in FPGA power consumption.

Compared to FPGAs, microcontrollers consume less power and have clock frequencies of a few to tens of megahertz. Furthermore, microcontrollers have power-saving or idle modes to further aid in lowering power consumption. Certain models have sleep currents of less than 1 µA and can operate at low clock speed in sec or Hz

Flexibility and customization

Due to their programmable architecture, FPGAs offer a great deal of flexibility and customization, enabling designers to craft unique digital circuits that meet their unique needs.

From straightforward logic gates to intricate digital signal processing algorithms, an FPGA’s logic blocks interconnects, and I/O blocks can be programmed to perform a broad range of digital functions. 

Because of its flexibility, it is possible to update or solve hardware issues without having to physically replace the device and to design quickly and iteratively.

FPGAs also provide a high degree of adaptability for changing application requirements since they can be reprogrammed to do new jobs by modifying their internal connections and logic.

Microcontrollers provide a great deal of software customization flexibility, but their hardware customization capabilities are not as extensive as those of FPGAs.

The code that a microcontroller’s CPU runs defines much of its functionality; this code is easily updated or modified to add new functionality or fix software faults.

Rapid development and testing are made possible by this software-based customization, which also makes it possible to modify the microcontroller’s functionality without affecting the hardware in response to changing requirements. 

Furthermore, a range of integrated peripherals, including timers, ADCs, and communication interfaces, are frequently included with microcontrollers. These peripherals can be adjusted to meet the needs of particular applications.

Cost

Due to their widespread use and maturity, most microcontrollers use fewer gates than FPGAs, and their prices range from a few dollars to tens of thousands of dollars.

Because FPGAs require more silicon because they have more logic gates than microcontrollers, they are usually more expensive. Furthermore, FPGAs are unable to reduce production costs because they are not as widely used as Microcontrollers.

Technology

Transistors based on CMOS technology form the basis of both microcontrollers and FPGAs. Yet each uses a different method to process the final data.

An instruction set that runs on the processor is called machine code (.hex file), and a microcontroller has one or more processing cores (CPU) in addition to program memory in the form of ferroelectric RAM and NOR flash.

However, there are various technologies available to program the FPGAs in memory-based FPGA programming, such as SRAM-based, flash-based, and one-time programmable-based FPGAs. The designer then uses a tool to convert the RTL code into a .bit file. This file was later utilized to program the FPGA.

Conclusion

There are benefits and drawbacks to FPGAs. Depending on the use case. As compared to microcontrollers, they typically allow engineers more access to hardware design and the chance to investigate integrated circuits.

However, a certain amount of expertise and experience are needed for this. Nonetheless, gaining a thorough understanding of embedded design engineering may be worthwhile.

Microcontrollers and processors give software expertise, whereas FPGAs offer hardware expertise. Additionally, experience makes it easier with time, just like when you first start writing code from scratch.

In conclusion, diverse applications can benefit from the distinct benefits and challenges that FPGAs and microcontrollers offer.

Microcontrollers have a simpler development process and use less power than FPGAs, but FPGAs are better at parallel processing workloads and allow a great degree of hardware customization.

It is crucial to take into account aspects like cost, development time, performance, power consumption, adaptability, and the particular needs of the intended application while deciding between various technologies.
