Consumption

Abstract—This paper presents a pioneer VLIW architecture of a native Java processor. We show that, thanks to the specif-ic stack architecture and to the use of the VLIW technique, one is able to obtain a meaningful reduction of energy con-sumption, with small area overhead, when compared to other ways of executing Java in hardware. The underlying tech-nique is based on the reuse of memory access instructions, hence reducing power during memory or cache accesses. The architecture is validated for some complex embedded applica-tions like IMDCT computation and other data processing benchmarks. Up to 3 times of savings in energy consumption is presented, when comparing the pipelined Java architecture against a VLIW version of the same processo
