Summary :

Media processing has become one of the dominant computing workloads. In this context, SIMD instructions have been introduced in current processors to raise performance, often the main goal of microprocessor designers. Today, however, designers have become concerned with the power consumption, and in some cases low power is the main design goal (laptops). In this paper, we show that SIMD ISA extensions on a superscalar processor can be one solution to reduce power consumption and keeping a high performance level. We reduce the average power consumption by decreasing the number of instructions, the number of cache references, and using dynamic power management to transform the speedup in performance in power consumption reduction.
