When parallelizing complex multimedia processing on multiple processors, the stochastic timing behavior should be carefully studied. Although there are already many papers on the performance analysis of stochastic parallel system, they are not targeted on multimedia processing. In this paper, first we study H.264/AVC encoder (running on x86) and QSDPCM(More)
Efficient use of an optimized custom memory hierarchy to exploit temporal locality in the memory accesses on array signals can have a very large impact on the power consumption in embedded data dominated applications. Only recently effective formalized techniques to deal with this specific task have been addressed. They work well for homogeneous signal(More)
Efficient exploitation of temporal locality in the memory accesses on array signals can have a very large impact on the power consumption in embedded data dominated applications. The effective use of an optimized custom memory hierarchy or a customized software controlled mapping on a predefined hierarchy, is crucial for this. Only recently effective(More)
