What is an FPGA?

FPGA (Field-Programmable Gate Array) is a field programmable gate array. It is a further development product based on programmable devices such as PAL, GAL, and CPLD. It appears as a semi-custom circuit in the field of application-specific integrated circuits (ASIC), which not only solves the shortcomings of custom circuits, but also overcomes the shortcomings of the limited number of gates in the original programmable devices.

#The development of FPGA is very different from the development of traditional PCs and microcontrollers. FPGA is mainly based on parallel operations and is implemented with hardware description language. Compared with the sequential operation of PC or microcontroller (whether it is von Neumann structure or Harvard structure), it is very different, which also makes it difficult to get started with FPGA development. FPGA development needs to start from many aspects such as top-level design, module layering, logic implementation, software and hardware debugging, etc.
