Acompanhando a popularização dos equipamentos portáteis e o rápido crescimento do tamanho dos sistemas elétricos, metodologias eficientes de projeto de baixo consumo de energia têm sido altamente exigidas. Para satisfazer essas solicitações, uma análise de potência altamente precisa e eficiente em níveis de abstração mais elevados é muito importante. O ambiente de design é composto por algoritmos eficientes de modelagem de energia, construção de biblioteca de energia e extração de dados. Esses componentes do ambiente devem ser equilibrados para total eficiência e precisão. Propusemos um novo ambiente de modelagem de energia eficiente que utiliza uma tabela de consulta (LUT). Reduz drasticamente o tamanho do LUT, em comparação com algoritmos convencionais. Isso torna a análise de energia e a construção de bibliotecas altamente eficientes. Os resultados experimentais mostram que nossa abordagem reduz o tempo de cálculo para construir a biblioteca para um décimo, mantendo a precisão da análise de potência. O erro RMS e o maior erro foram inferiores a 8.30%, 59.16%, respectivamente.

Abstract: Accompanying with the popularization of portable equipments, and the rapid growth of the size of the electric systems, efficient low power design methodologies have been highly required. To satisfy these requests, a high accurate and high efficient power analysis in higher abstraction level is very important. The design environment is composed by efficient algorithms of power modeling, power library building, and data extracting. Those components of the environment should be balanced for the total efficiency and accuracy. We have proposed a new efficient power modeling environment which uses a look-up table (LUT). It reduces the size of the LUT drastically, compared to conventional algorithms. It makes the power analysis and library building high efficient. The experimental results show that our approach reduces the computation time to build the library to one tenth while keeping the accuracy of the power analysis. The RMS error and the largest error has been less than 8.30%, 59.16%, respectively.
