为了减少测试数据量,提出基于交替-连续长度码的测试数据编码方法。采用变长-变长的编码方式,直接编码测试集中连续-交替的长度码。实验结果表明,该方法的解压结构是一个简单的有限状态机,所需额外硬件开销小,与同类型的编码方法相比,具有更高的测试数据压缩率。 In order to reduce the amount of test data, a test data coding method based on alternating-continuous length codes is proposed. Variable length - variable length encoding, direct encoding test set continuous - alternating length code. Experimental results show that the decompression structure of the proposed method is a simple finite state machine, which requires less additional hardware overhead and has higher compression ratio of the test data than the same type of coding method.
