Instantiating Uninterpreted Functional Units and Memory System: Functional Verification of the VAMP

Sven Beyer, Christian Jacobi, Daniel Kroening, Dirk Leinenbach, Wolfgang J. Paul

Abstract: In the VAMP (verified architecture microprocessor) project we have designed, functionally verified, and synthesized a processor with full DLX instruction set, delayed branch, Tomasulo scheduler, maskable nested precise interrupts, pipelined fully IEEE compatible dual precision floating point unit with variable latency, and separate instruction and data caches. The verification has been carried out in the theorem proving system PVS. The processor has been implemented on a Xilinx FPGA.
