Application of group and expansion code in test data compression
组扩展编码在测试数据压缩中的应用

A scheme of test data compression based on the Group and Expansion Code (GEC) was presented to reduce compression data of System-on-a-Chip (SoC). It is a variable-to-variable code based on encoding both 0's run and 1's run, and the code word consists of marked bit, prefix and tail. Due to the characteristics of GEC, which lies in its ability to double capacity of every group, it can compress test data efficiently. Theoretical analysis and experimental results show that the proposed scheme can provide a high...
