1. What is FPGA in embedded systems?
FPGA in embedded system is a solution that integrates FPGA technology into embedded system. An embedded system is a computer system designed for a specific application, which usually includes components such as processor, memory, peripheral interface, etc., which are used to control, monitor or perform specific tasks. Combining FPGA with embedded system can bring a series of significant advantages.
FPGA (Field Programmable Gate Array) is a programmable logic device, which consists of a large number of programmable logic units and programmable interconnection resources. It has the characteristics of flexibility and reconfigurability, and is widely used in communication, digital signal processing, embedded systems and other fields. The basic structure of FPGA includes programmable input and output units, configurable logic blocks, digital clock management modules, embedded block RAM, wiring resources, embedded dedicated hard cores and bottom embedded functional units. The design of FPGA can be implemented through hardware description language, which has high flexibility. -
2. Is FPGA a controller or a processor?
FPGA is a programmable integrated circuit. It is neither a traditional controller nor a traditional processor, but a device between the two. FPGAs are programmed with hardware description languages and can customize circuits according to requirements, making them suitable for application scenarios that require flexible configuration and high performance.
The difference between FPGAs and microcontrollers (MCUs) and central processing units (CPUs) lies in their flexibility and application scenarios. MCUs and CPUs are usually microcontrollers and processors with preset functions, suitable for environments that perform single tasks and require efficient execution. FPGAs, on the other hand, have higher flexibility and reconfigurability, can be programmed and reprogrammed according to specific applications, and are suitable for applications that require high customization and optimized performance.
The advantages of FPGAs include their high flexibility and reconfigurability, which makes them ideal for applications that require frequent updates or optimization of logic. Compared with application-specific integrated circuits (ASICs), FPGAs do not require permanent design fixes on silicon, so new features can be developed and tested or bugs can be fixed more quickly.

3. Is FPGA a microprocessor?
FPGA is not a microprocessor. FPGA (Field-Programmable Gate Array) is a special digital circuit that is mainly used to implement complex logic functions, while microprocessors are processors used to execute instructions.
FPGA and microprocessors have significant differences in function and use. FPGA is a semi-custom digital circuit that can be programmed during the hardware design stage to implement specific logic functions. FPGA solves the shortcomings of customized circuits and overcomes the shortcomings of the limited number of gate circuits of the original programmable devices. It is suitable for occasions that require highly customized logic functions. In contrast, a microprocessor (such as a CPU) is a general-purpose computing device used to execute instructions stored in it, process data, and perform computing tasks. Microprocessors include MCU (microcontroller), DSP (digital signal processor), etc., each of which has different application scenarios and functional characteristics.
Specifically, FPGA and microprocessor are also different in structure and working mode. FPGA consists of a large number of programmable logic units, and users can program to implement any logic function as needed. Microprocessors contain a central processing unit (CPU), memory, and input and output interfaces to execute predefined instruction sets, process data, and perform computing tasks. In addition, FPGAs are usually used in situations that require high-speed processing and parallel computing, such as communications, image processing, etc., while microprocessors are widely used in various computing devices and systems. -
4. Why use FPGA as a digital controller?
The main reason for using FPGA as a digital controller is its flexibility and programmability. FPGA (Field Programmable Gate Array) is a chip whose internal structure can be changed through programming. It has high flexibility and programmability, which makes FPGA widely used in the field of digital controllers.
The flexibility of FPGA is reflected in the fact that its logic units can be configured to implement different logic functions. Users can use hardware description languages (such as VHDL or Verilog) to write programs to map logic functions to lookup tables (LUTs) and logic units inside FPGA. This flexibility allows FPGAs to adapt to different application requirements and can be reprogrammed as needed to adapt to new application scenarios.
In addition, FPGAs also have high-performance parallel computing capabilities and high-speed data processing capabilities, which makes it play an important role in digital signal processing, image processing, network communication and other fields. The parallel processing capabilities of FPGAs enable it to handle multiple tasks at the same time, improving overall processing efficiency.
