| Popis: | 100 In this paper, we propose an imprecise radix-4 adder for image processing of multimedia applications. In order to reduce power consumption of the architecture and maintain acceptable image quality, we utilize the relaxtion of numerical accuracy in error tolerant to reduce the logic of radix-4 adder complexity. Based on TSMC 90nm CMOS technology, the simulation results indicate that dynamic power saving is 13~24%, 14~22% reduction in leakage, and the image quality degradation is minor campared to the previous researches respectively. |
