…processing abilities. An FPGA configuration is generally written using a hardware description language (HDL), e.g., VHDL, similar to the ones used for application-specific integrated circuits (ASICs). Circuit diagrams were formerly used to write the configuration. The logic blocks of an FPGA can be configured to perform complex combinational…
