Abstract: In the test data post-processing,the single-thread data post-processing parsing method easily causes to the main thread block,with a low efficiency.In order to improve the parsing efficiency,a muti-thread processing method based on data decomposition is proposed.The data to be processed is divided into multiple independent data blocks,and then each core processes different data blocks for format processing and file writing respectively.The full potential of multi-core computer can be realized to complete data post-processing,which can shorten the post-processing time and improve the utilization rate of computer resources.In this way,the detailed data results can be given as soon as possible after test,to support the data interpretation.

Key words: Test data, Data analysis, Multi-thread, Data decomposition
