摘要
为了提高数据的传输效率,同时保证压缩后信息的完整性,本文基于 DSP 对实时数据无损压缩算法实现的具体方法和关键技术,从硬件和软件两个方面进行了相关分析,并对无损压缩的相关算法进行了比较。采用算术编码(ARC)进行了相应的压缩。最后通过实验,对压缩时间和压缩去除率进行了分析。结论证实本方案切实可行,各项指标满足系统要求。
In order to enhance the data transmission efficiency, and guarantee the integrity of the compressed information,this paper analyses the implementation of real-time data lossless compression in hardware and software based on DSP. It also compares relevant algorithms of lossless compression. Arithmetic coding （ARC） is used to carry on the corresponding compression. Finally, the experiment carries on the analysis to the time of compression and the compression elimination rate. The result eonfirmes that this plan is practical and feasible, all of its targets satisfie the system＇s request.
