| 摘 要： | 提出一种相对游程长度编码方案,以在不增加待编码数据中游程数量的情况下,达到减少待编码游程长度的目的,即通过缩短代码字长度来提高压缩效果。对ISCAS89部分基准电路的实验结果显示,提出的方案在压缩效率和解压结构方面都明显优于Golomb码、FDR码、EFDR等同类方案。

| Abstract: | A coding scheme of relative length of runs was presented. It reduces the length of runs needing to be encodedby not increasing the number of runs in encoded test data. So the compression effect is enhanced by shortening thelength of codeword. Experimental results on some ISCAS 89 benchmark circuits show that the proposed scheme obvi-ously outperforms the traditional coding methods in the compression ratio and the implementation of decompression,such as Uolomb, FDR, EFDR coding. |
