Abstract

A 0.5V, 10MHz, 9mW image processor with 320 processing element (PE) SIMD and a 32bit CPU has been developed using 40-nm CMOS. High voltage clock distribution (HVCD) reduces the number of excessive hold buffers required in a 0.5-V logic circuit design, thereby reducing the area, delay, and energy of the SIMD by 14 %, 13%, and 6%, respectively. The 0.5-V SIMD with HVCD achieves an energy efficiency of 563 GOPS/W (= 4.26mW at 7.5MHz), the highest yet reported for near-threshold SIMD. In addition, adaptive frequency scaling (AFS), used to mitigate the impact of the ripple of a buck converters, increases average clock frequency by 33%.
