Abstract

Multimedia applications are characterized by an increased number of data transfers and storage operations. Appropriate transformations can be applied at the algorithmic level to improve crucial implementation characteristics. In this paper, the effect of data-reuse transformations on power consumption and performance of multimedia applications, realized on General Purpose (GPP) and Application Specific Instruction set Processors (ASIP), is examined. An ASIP for multimedia applications, designed based on a complete methodology, and the ARM9TDMI are used to evaluate this effect. Results prove the efficiency of the ASIP solution and indicate that both GPP and ASIP approaches can benefit, from such transformations, in terms of energy consumption and performance.
