摘要
在对信号进行分析处理时,经常使用逻辑分析仪设备对被测信号进行采集分析,采集数据将在上位机进行存储;如果直接存储,无疑将占用大量的存储空间,为了解决逻辑分析仪采集数据量大、数据直接存储占用空间大的问题,文章以AMC2511逻辑分析仪和码型发生器为硬件平台,详细研究了数据的各种无损压缩算法,并根据采集数据本身的特点,提出了RLE和LZW算法相结合的设计思路;通过对采集数据进行压缩试验,总结出该算法在获取大的压缩比的同时,缩短了压缩时间。
The logic Analyzer is often used to sample the signal when analyzing it. It will occupy large amount of memory if directly stored. To solve the problem of the large quantity of data sampled by the Logic Analyzer and the enormous memory space if directly stored, some kinds of compression algorithms are compared in detail based on the AMC2511 Logic Analyzer and code generator. From the research on the sampled data and the result of the test, the data can be compressed more with shorter time if the RLE algorithm combined together with LZW algorithm is used.
