| 摘 要： | 随着嵌入式系统的发展,在性能不断提高的同时,软件代码规模也不断扩大.而超长指令字结构更加引起了代码的膨胀,因此代码压缩技术变得很重要.本文基于自主研发的SDSP处理器核,应用3种压缩编码技术,比较它们压缩的效果,并讨论了包括压缩后地址的重映射以及解压缩结构的整体硬件方案.

| Abstract: | Along with the progress of embedded system's performance,its code size is being much bigger.The new VLIW DSP structure leads code compression more important,In this paper,we use three code compression technology based on the DSP core which is designed ourselves Final,we compare their compression effects,and study the address remapping affer compression and the construct of decompression. |
