| 摘 要： | 提出了一种新的交替变游程编码的测试数据压缩方案。不像其它文章中仅仅编码连续的"0",该方案采用变长到变长的编码方式对0游程和1游程进行编码。实验数据表明,交替变游程编码能取得较高的压缩效率,能够显著减少测试时间和测试功耗,从而达到降低测试成本的目的。

| Abstract: | A new test data compression technique based on alterating variable run-length coding is proposed.It is a variable-to-variable-length code based on encoding lengths of runs of 0s and 1s without limitation on runs of 0s as proposed.Experimental results show that this code can provide a high compression ratio and it also leads to a significant saving in test time,peak and average power,which results in reducing test cost. |
