摘要
介绍了一种遥测数据实时压缩系统的设计方案,该设计以FPGA+DSP为硬件架构,以具有一阶差分预测的ARC编码为无损压缩方案,达到了较高的压缩去除率和较快的压缩速度,适合在可靠性要求较高的遥测系统中使用。经实验验证,无损压缩系统有效地缓解了遥测系统的传输带宽压力。
A kind of telemetry data real-time compression system is introduced, this design with FPGA ＋ DSP for hardware architecture, with first-order difference prediction ARC coding for lossless, the system achieve high compression removal efficiency and faster compression speed, it＇s suitable for high reliability requirements telemetry system. The results of experiment show that the lossless compression system effectively alleviates the transmission bandwidth pressure of telemetry system.
