摘　　要：文章对CCSDS包处理器模型进行了改进,并分析了其性能界限,给出了影响包处理器性能的主要因素;通过分析输入缓存器和处理缓存器不同的状态,得出包处理器处理能力的上限,指出处理器能支持的帧数超过包处理器能够缓存的帧数之后的帧数据丢失隐患,以此界定了何种情况下包处理器需要转存遥测包数据;并对CCSDS数据包的整个处理流程进行了描述。A model of CCSDS telemetry packet processing is improved in this paper. According to the model, the critical condition of CCSDS telemetry packet processing is analyzed to point out the main factor of affecting the performance of CCSDS telemetry packet processing. The upper limit of the performance of processor is discussed by the analysis of input buffer and process buffer status. The threshold of CCSDS telemetry packet processing is discussed, and according to this threshold, the telemetry packet data will be stored. The implementation of CCSDS telemetry packet processing on the ground is described particularly.
