Window operations which are computationally intensive and data intensive are frequently used in image compression, pattern recognition and digital signal processing. The efficiency of memory accessing often dominates the overall computation performance, and the problem becomes increasingly crucial in reconfigurable systems. The challenge is to intelligently exploit data reuse on the reconfigurable fabric (FPGA) to minimize the required memory or memory bandwidth while maximizing parallelism. In this paper, we present a universal memory structure for high level synthesis to automatically generate the hardware frames for all window processing applications. Comparing with related works, our approach can enhance the frequency from 69MHZ to 238.7MHZ.
