A 100 MHz, 0.4 W RISC processor with 200 MHz multiply adder, using pulse-register technique

Abstract

Recent emergence of various multimedia systems requires microprocessors to have features like high-performance, low power dissipation, and signal processing capabilities altogether. The 118MIPS RISC processor presented in this paper has a multiply-adder which is essential for signal processing applications. Using a pulse register and on-demand clock distribution, a 100 MHz, 428 mW 32 b RISC processor with 200 MHz multiply-adder is achieved.
