Abstract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.
Other AbstractThis paper presents a high performance image compressor for onboard space image,based on CCSDS algorithm[1] 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 erage data rate of 40dB with 8:1 compression ratio and 30dB plus with 16:1 compression ratio, and a maximnum data rate of 15.2Mpixels/s is sustained at 5OMHz.
