摘要
在现有可重构协处理器设计实现的基础上,根据图像处理算法的特点,提出了一种改进的可重构协处理器结构IRC。在IRC中,采用了一种基于网格的网络结构与行(列)SIMD的工作模式,使得图像处理算法的执行效率得到提高。在典型的图像处理应用中,IRC能够达到通用处理器的7倍以上的速度。
An improved architecture of reconfigurable coprocessor is presented based on the feature of image processing algorithms, that is IRC (Image Reconfigurable Coprocessor). In this architecture, a 2D mesh-based network and a colunm-SIMD working mode are used, which improve the efficiency of image processing algorithms. The simulation results show that IRC achieves much higher performance with 7x factor.
