The microprocessor is one of the most important blocks of the SoC. Considering high-performance, we implement a 32-bit RISC microprocessor, named as FDU32, with instruction sets compatible with ARM7TDMI. By using 5-stage pipeline and improving the circuit structure, FDU32 obtains 67% increment in max clock rate, 11% reduction in CPI and 86% increment in MIPS compared with ARM7TDMI at the same 0.35 /spl mu/m CMOS process, and only the transistor count increases a little. FDU32 has passed the FPGA verification and taped out.
