| 摘 要： | 文章提出了一种混合定变长虚拟块游程编码的测试数据压缩方案,该方案将测试向量级联后分块,首先在块内找一位或最大一位表示,再对块内不能一位表示的剩下位进行游程编码,这样减少了游程编码的数据量,从而突破了传统游程编码方法受原始测试数据量的限制.对ISCAS 89部分标准电路的实验结果显示,本文提出的方案在压缩效率明显优于类似的压缩方法,如Golomb码、FDR码、VIHC码、v9C码等. |

| Abstract: | A test data compression scheme based on mixed fixed and variable run-length coding in virtual block(MFVR-CVB) is presented.In the scheme the test vectors are concatenated to a stream first and then this stream is divided fixed length block.In every block the one-bit-representation or the maximum one-bit-representation is search to reduce the number and length of runs.Then the left data in every block is encoded by using the run-length encoding.This reduces the volume of data needed to be encoded and breaks ... |
| Keywords: | test data compression coding fixed length coding variable length coding |
