摘要

<FONT face=Verdana>本文给出了一种采用Handel-C设计理念，基于CCSDS图像压缩算法的硬件图像压缩核的设计过程. 算法实现过程中充分利用Handel-C语言的硬件并行实现机制，在各个硬件模块间大量采用并行运算和流水结构，提高了芯片的处理速度. 实验数据表明，本文压缩核的设计在资源消耗和码速率两方面取得了很好的折中. 在频率为50MHz的情况下，码速率可以达到15.2Mpixels/s；在8倍压缩情况下，平均PSNR接近40dB，16倍压缩情况下，平均PSNR超过30dB.

Abstract

<FONT face=Verdana>This paper presents a high performance image compressor for onboard space image

based on CCSDS algorithm by using Handel-C language. The hardware solution proposed here exploits many parallel architectures and pipeline techniques under the Handel-C language′s hardware mechanism

thus effectively improves compressing speed. A testing system is introduced to verify the design and the experimental results indicate that this core is a very good middle course between chip resource and speed. The average PSNR can be achieved to near 40dB with 8:1 compression ratio and 30dB plus with 16:1 compression ratio

and a maximum data rate of 15.2Mpixels/s is sustained at 50MHz.
