摘　　要：提出了一种新的测试数据压缩方法,它能有效地压缩测试数据。首先将整个测试集划分成若干定长块,对非全0/1块,使用折半的方法划分;对全0/1块,使用标记位来表示划分的次数。与传统的编码压缩方法相比,它只需要记住数据块被折半划分的次数就可表示其长度,同时还具有硬件解压结构和通信协议简单的优势。A new test data compression scheme was proposed, which can reduce the test data volume effectively. Firstly,the whole test set was partitioned to several length-fixed blocks. For non-0/1 data block it used dimidiation technique, and for 0/1 data block it used some mark-bits to represent the times of partitioning. Compared with the traditional data-coding methods, the proposed scheme only needs to know the times of partitioning to express the data length. At the same time, the proposed scheme uses simpler circuit structure and communication protocol to decompress the coded test data.
