À medida que a tecnologia diminui, a energia de fuga representa uma proporção maior da energia total. Aplicando o sonolento técnica para um cache, é considerada uma das técnicas mais eficientes para reduzir a energia de vazamento. Porém, aumenta a Taxa de Erro Suave (SER), portanto, muitos pesquisadores duvidam da confiabilidade da técnica sonolenta. Neste artigo, mostramos vários motivos pelos quais o cache de instruções pode adotar a técnica sonolenta sem problemas de confiabilidade. Primeiro, um cache de instruções sempre armazena dados somente leitura, levando à recuperação de erros suaves ao buscar novamente as instruções na memória de nível inferior. Em segundo lugar, o efeito da nova busca causada por erros leves no desempenho é insignificante. Além disso, uma porcentagem considerável de erros de software pode ocorrer sem prejudicar o desempenho. Por último, erros de software irrecuperáveis podem ser controlados pelo esfregando método. Os resultados da simulação mostram que o cache de instruções lento raramente aumenta a taxa de erros irrecuperáveis e degrada de forma insignificante o desempenho.

Abstract: As technology scales down, leakage energy accounts for a greater proportion of total energy. Applying the drowsy technique to a cache, is regarded as one of the most efficient techniques for reducing leakage energy. However, it increases the Soft Error Rate (SER), thus, many researchers doubt the reliability of the drowsy technique. In this paper, we show several reasons why the instruction cache can adopt the drowsy technique without reliability problems. First, an instruction cache always stores read-only data, leading to soft error recovery by re-fetching the instructions from lower level memory. Second, the effect of the re-fetching caused by soft errors on performance is negligible. Additionally, a considerable percentage of soft errors can occur without harming the performance. Lastly, unrecoverable soft errors can be controlled by the scrubbing method. The simulation results show that the drowsy instruction cache rarely increases the rate of unrecoverable errors and negligibly degrades the performance.
