O processamento de mídia tornou-se uma das cargas de trabalho de computação dominantes. Neste contexto, instruções SIMD foram introduzidas nos processadores atuais para aumentar o desempenho, muitas vezes o principal objetivo dos projetistas de microprocessadores. Hoje, porém, os projetistas estão preocupados com o consumo de energia e, em alguns casos, o baixo consumo de energia é o principal objetivo do projeto (laptops). Neste artigo, mostramos que extensões SIMD ISA em um processador superescalar podem ser uma solução para reduzir o consumo de energia e manter um alto nível de desempenho. Reduzimos o consumo médio de energia diminuindo o número de instruções, o número de referências de cache e usando o gerenciamento dinâmico de energia para transformar a aceleração do desempenho em redução do consumo de energia.

Abstract: 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.
