人们对基于现场可编程门阵列的易于编程的高性能图像处理平台提出了更高的要求。在之前的工作中,我们开发了一款新型的高性能处理器IPPro,并在Xilinx Zynq平台上进行了定向梯度直方图(HOG)算法的研究。在这里,我们确定和探索了一些映射策略来提高软核的处理效率,以及一些用于创建除法协处理器的选项。这一点在Zynq平台上的修订后的高清HOG实现中得到了演示,性能为328 FPS,比最初的实现速度提高了146%,能耗降低了10倍。
There is demand for an easily programmable, high performance image processing platform based on FPGAs. In previous work, a novel, high performance processor - IPPro was developed and a Histogram of Orientated Gradients (HOG) algorithm study undertaken on a Xilinx Zynq platform. Here, we identify and explore a number of mapping strategies to improve processing efficiency for soft-cores and a number of options for creation of a division coprocessor. This is demonstrated for the revised high definition HOG implementation on a Zynq platform, resulting in a performance of 328 fps which represents a 146 % speed improvement over the original realization and a tenfold reduction in energy.
