Cache Performance Analysis based on the EDMA Transfer Chain

摘要：

　　This paper discusses the use of EDMA in real time image processing systems, high-resolution panoramic vision unfolding system based on TMS320DM642, which continuously update dynamic image data in ping-pong cache.And analyze the cache performance.The cache strategy is based on the channel chaining capability of the EDMA channel controller.Each EDMA transfer synchronized with another transfer.Then the CPU would continuously process the cached data and do not pay attention to any synchronization of each EDMA channel.This cache strategy can obtain the highest performance in DSP system.
