基于Vivado HLS的边缘检测硬件加速应用

摘要

针对计算机处理高清图像或视频的边缘检测时存在延时长和数据存储带宽受限的缺点,提出了用VivadoHLS将边缘检测软件代码转换成RTL级硬件电路的硬件加速方法.硬件加速是将运算量大的功能模块由硬件电路实现,根据硬件电路工作频率高和数据位宽自定义,可以解决延时长和数据宽度受限的缺点.实验结果表明,边缘检测硬件加速方法不仅使延时和数据带宽都得到了改善,而且也缩短了边缘检测的开发周期.%For the issues of large delay and data storage limited by the bandwidth in the handling of high-definition images and video edge detection by computer,an optimized hardware acceleration design scheme using Vivado HLS transform edge detection software code into the RTL hardware circuit is proposed.Hardware acceleration is the computation of function module by the hardware circuit implementation,which is to solve the delay and data bandwidth constrained defect based on the hardware circuit with high working frequency and the custom data width.The results prove that the edge detection hardware acceleration method not only improved in both time delay and data bandwidth,but also shorten the development cycle of the edge detection.
