High-speed and low-power DSPs have been developed for versatile application
s, especially for digital communications. These DSPs contain a 16-bit fixed
point DSP core with multiple buses, highly tuned instruction set and low-p
ower architecture, featuring 0.45 mA/MIPS, 100-120 MIPS performance by a si
ngle CPU core, 200 MIPS performance by dual CPU core architecture, respecti
vely and also contain a 1.2 V low-voltage DSP core with 30 MIPS performance
for super low-power applications. In this paper, new architecture VIA2 pro
gramming ROM for high-speed and new D flip-flop circuit considering the imp
act of pocket implantation process for low power are discussed, including k
ey C-MOS process technology.
