HYBRID-ARCHITECTURE COMPUTER combines a general-purpose microprocessor and reconfigurable FPGA chips. The dynamic instruction set computer (DISC), built at Brigham Young University to demonstrate mixed architecture advantages, consists of two FPGAs and memory on a circuit board connected to a personal computer. The controller FPGA loads circuit configurations stored in the memory onto the processor FPGA in response to the requests of the operating program. If the memory does not contain a requested circuit, the processor FPGA sends a request to the PC host, which then loads the configuration for the desired circuit.
