Abstract(in English) | This paper presents a novel system-level approach that minimizes the energy consumption of embedded core-based systems through datapath width optimization. It is based on the idea of minimizing energy consumed by redundant bits, which are unused during execution of programs by means of optimizing the data path width of processors. To minimize the redundant bits of variables in an application program. the effective size of variables is determined after variable size analysis, and Valen-C language is used to preserve the precision of computation. Analysis results of variables show that there are average 39% redundant bits in MPEG-2 decoder C source program. In our experiments for several embedded applications. energy savings without performance penalty are reported range from about 10.0% to 48.3%. |
