CCSDS接收端包处理性能分析与仿真

摘要

建立了CCSDS接收端包处理器的性能模型及处理界限,分析了缓存容量和处理速度对包处理器处理能力的影响.理论分析和仿真结果表明,增大缓存容量或提高处理速度,都可以在一定程度上防止数据的溢出,但一个必要条件是处理器的处理速度要大于输人数据流的每帧平均包数,这为接收端处理系统的设计提供了理论依据.%The paper establishes the performance model and processing limit of CCSDS receiver packet processor, analyzes the impact of cache capacity and processing speed to packet processing capability.Theory analysis and simulation results show that increasing cache capacity or improving processing speed can avoid data overflow, however, processing speed should be greater than the average number of packets within every frame of input data stream, which provides a theoretical basis for design of the receiver processing system.
