测试数据编码压缩技术研究

Researching Based on Test Data Coding Compression Technology

介绍了测试数据编码压缩技术的原理、特点及技术要求,并根据编码原理对常见的测试编码压缩技术进行分类,研究了每一类编码压缩技术的优势及局限性,最后提出了一种基于纵向分组对比的分块编码思想。这种分块编码思想是将测试集按固定宽度分成若干组,沿纵向对比编码,这种将测试集化整为零的措施有利于提高数据块间的相关性及压缩率,同时为进一步研究测试数据的编码压缩技术提供了新的思路。

This paper describes the principles, characteristics and technical requirements about test data compression coding technology, then, classifies the technology according to coding theory, and studies the advantages and limitations of each type of compression coding technology, finally , presents a blocking code idea based on vertical grouping and contrasting, according to which, the test set is divided into sevcral groups, encoded along vertical. This approach is conducive to improve the correlation between data blocks and compression ratio, at the same time, provides inspiration to further study of test data compression coding technology.
