What is fpga?

FPGA is a chip that can change its internal structure through programming. Generally, FPGA engineers will use hardware description language Verilog or VHDL to "program" the FPGA, and then synthesize, lay out and route it through FPGA development tools (Diamond or Radiant) provided by manufacturers to generate bit files or bin files.

Advantages of FPGA

FPGA is composed of logic unit, RAM, multiplier and other hardware resources. By reasonably organizing these hardware resources, hardware circuits such as multipliers, registers and address generators can be realized. FPGA can be designed using block diagram or VerilogHDL, from simple gate circuits to FIR or FFT circuits.

FPGA can be reprogrammed infinitely, and it takes only a few hundred milliseconds to load a new design. Reconfiguration can reduce hardware overhead. The working frequency of FPGA is determined by the FPGA chip and design, and some harsh requirements can be met by modifying the design or replacing a faster chip (of course, the working frequency can not be improved indefinitely, but is restricted by the current IC technology and other factors).
