Abstract:
An apparatus comprising programmable logic devices including a field programmable gate array (FPGA) is presented. In one embodiment, the apparatus also comprises a programmable read only memory (PROM) to store a firmware which includes at least a system boot code and a configuration code. The apparatus further includes a configuration agent to configure the FPGA by using the configuration code and to release the reset to the CPU after the FPGA is configured. In one embodiment, the configuration agent comprises a SPI-FPGA bridge (serial peripheral interface to FPGA configuration interface). In one embodiment, the configuration agent is operable to determine whether the FPGA is ready for configuration based at least on a status from the FPGA.
