摘要
随着高清视频处理技术的发展,高清视频的应用场合日益增长。为了适应高清视频后处理系统的需求,介绍了一种具备较为全面的高清视频后处理功能的ASIC设计,及其仿真验证技术。整个系统包括视频采集模块、视频调整模块、块效应滤波模块、DMA控制器、高清视频显示模块等,实现了从传感器采集高清视频,经过高清视频尺寸调整、视频旋转,完成对解码视频块效应滤波,对高清视频实现缓存显示控制的一整套后处理过程。设计采用软硬件联合验证技术,通过搭建的软硬件联合仿真平台完成功能测试。
With the development of image processing technology, the demands for HD video are increasing. In order to meet the requirement of HD video processing system, this paper introduces an ASIC chip meeting the HD video post-processing function, and the simulation and verification are carried on. The whole system consists of the HD video capture module, video convert module, de-blocking filter module, the DMA controller, HD video display module and so on. The main process includes capturing HD video data from a sensor, resizing and rotating the HD video, deblocking the decode video data, and displaying the HD video from the buffer. The design adopts software and hardware co-simulation to test the function by constructing the software and hardware co-simulation platform.
