Os eletrônicos de consumo móveis tradicionais, como reprodutores de mídia e smartphones, usam duas memórias distintas, SDRAM e memória Flash. A SDRAM é utilizada como memória principal por possuir característica de acessibilidade aleatória por unidade de byte, enquanto a memória Flash como armazenamento secundário devido à sua característica de não volatilidade. No entanto, o advento da memória de classe de armazenamento (SCM), que suporta características de memória SDRAM e Flash, oferece a oportunidade de projetar uma nova configuração de sistema. Neste artigo, exploramos quatro configurações de sistema viáveis, nomeadamente RAM-Flash, RAM-SCM, SCM-Flash e SCM-Only. Em seguida, utilizando um sistema embarcado real equipado com FeRAM, uma espécie de SCM, analisamos as compensações entre desempenho e eficiência energética de cada configuração. Resultados experimentais mostraram que o SCM tem grande potencial para reduzir o consumo de energia para todas as configurações, enquanto o desempenho é altamente dependente da aplicação e pode ser degradado na configuração SCM-Flash e SCM-Only.

Abstract: The traditional mobile consumer electronics such as media players and smart phones use two distinct memories, SDRAM and Flash memory. SDRAM is used as main memory since it has characteristic of byte-unit random accessibility while Flash memory as secondary storage due to its characteristic of non-volatility. However, the advent of Storage Class Memory (SCM) that supports both SDRAM and Flash memory characteristics gives an opportunity to design a new system configuration. In this paper, we explore four feasible system configurations, namely RAM-Flash, RAM-SCM, SCM-Flash and SCM-Only. Then, using a real embedded system equipped with FeRAM, a type of SCM, we analyze the tradeoffs between performance and energy efficiency of each configuration. Experimental results have shown that SCM has great potential to reduce energy consumption for all configurations while performance is highly application dependent and might be degraded on the SCM-Flash and SCM-Only configuration.

AB - The traditional mobile consumer electronics such as media players and smart phones use two distinct memories, SDRAM and Flash memory. SDRAM is used as main memory since it has characteristic of byte-unit random accessibility while Flash memory as secondary storage due to its characteristic of non-volatility.
