Description A systematic methodology has been developed for the reduction of the data transfers and storage related power consumption in realizations of multimedia applications on programmable multimedia processors. The methodology is based on the application of code transformations that move the main part of the memory accesses from the large (off-chip) memories to smaller ones (on-chip). Performance (in number of cycles) which is the overriding constraint for multimedia applications is improved in most cases by the application of the power optimizing code transformations as well. The main focus of this paper is on the effect of these power optimizing code transformations on the code size, an important design parameter that implicitly affects both the total system power consumption and the performance. Experimental results from real-life applications demonstrate that contrary to earlier conjectures, if applied well our methodology introduces only small code size penalties that do not offset the significant gains in both performance and power consumption achieved by its application.
