Memory Bank Conflict Reduction for Embedded Multimedia Applications

摘要

A detailed study of the impact of memory bank conflict on the performance of EMAs is presented. Based on the study, novel schemes utilizing SIMD and array padding are described to solve the memory bank conflict problem. Since the parameter in array padding has a great impact on the overall behavior of the memory system, how to achieve optimal padding is an important research topic. Here, we analyze the padding effect and develop a probabilistic model to determine the optimal padding distance. Preliminary experimental results are given to verify the correctness of this model.
