Abstract

A field programmable gate array (FPGA) has an interface circuit that allows signals to be transmitted directly between the FPGA and a processor. The processor interface (PI) of the FPGA enables the processor to access data at any time from either programmable logic of the FPGA or system registers of the PI. The present invention eliminates the need for external intermediate logic previously required to interface an FPGA and a processor.
