DSP-Based Parallel Processing Model of Image Rotation

Abstract

AbstractIn the DSP real-time image processing, large amounts of data exchange and memory operation limit efficiency of the program implementation. In order to improve the efficiency of DSP, a model of blocking and parallel processing is proposed in this paper; firstly the large binary image is divided into blocks according to the memory size of DSP, the block diagram is rotated by DSP in accordance with the mode of readout and processing and storing, and finally they are put together. So the data processing amount in DSP is not only reduced, the efficiency of the implementation process is but also improved
