Design and Effective Functional Verification of an Embedded Processor with SIMD Extension

An embedded processor with SIMD extension is presented. The processor contains 32-bit dual-issue RISC core with out-of order execution capability. A dedicated short-vector SIMD unit is extended to speed up the multimedia processing. Also an effective co-verification method is designed to verify the processor. It focuses on the architecture design and the verification of the embedded processor. The performance evaluation and the physical design are also discussed. The processor is fabricated by CMOS 180 ns technology with 1.42 MIPS@MHz and 7.9 mW@MHz.
