中文摘要: 针对目前利用软件解码图像不能满足实时性要求的现状，提出了一种基于FPGA 片上系统（SOPC）的JPEG 图像解压缩系统设计方案。主要介绍了JPEG 图像解压缩算法的硬件实现方法和系统的工作原理以及具体实现。结果表明，该系统能够加快图像的解码速度，解码一幅640×320 图像仅需要21.3ms，实时的实现了图像的解码。
Abstract:The method of using software to decoding image cannot satisfy the timely request. This paper proposes a system design plan of JPEG image decompression. It mainly gives the JPEG image decompression algorithm’s hardware realization and system’s principle of work as well as the hardware realization. The result indicates that this system can speed up the decoding speed of image only with 21.3ms when decoding a 640×320 image. It realizes the image decoding timely.
