摘　　要：为了满足军事通信系统对无线电台多制式通信的需求,设计了一种基于多核DSP TMS320C6678的多制式通信信号处理模块,采用主从处理模型进行并行设计,采用本地模式和远程模式进行动态重构设计;以并行处理技术和可重构技术为核心进行研究,并对该模块进行测试,使用开发工具CCS对多核DSP中各核处理数据进行跟踪,其波形显示多核同时进行着各自的任务;并对核x进行数据跟踪,其波形显示核x数据发生改变。结果表明:该模块实现了多种调制解调方式的并发执行,达到无线电台多制式通信需求;实现了调制解调方式的动态重构,达到无线电台的可扩展性和兼容性需求。本文的设计简化了电台硬件结构,促进了各种电台之间的相互兼容和通信。In order to meet the requirements of military communication system for multi-mode communication of radio stations,a multi-mode communication signal processing module based on multi-core DSP TMS320C6678 is designed.The parallel processing technology and reconfigurable technology are the core,the master-slave processing model is used for parallel design,and the local and remote modes are used for dynamic reconfiguration design.The module is tested,and the core processing data of the multi-core DSP is tracked by using the development tool of CCS,and the waveform shows that the multi-core performs its respective tasks at the simultaneously.It indicates that the module implements concurrent execution of multiple modulation and demodulation to meet the multi-mode communication requirements of radio stations.And by using CCS to track the core x data is tracked,the changes of core x data waveform indicate that the core x data processing mode changes.It shows that the module realizes the dynamic reconfiguration among different modulation and demodulation mode,which meets the scalability and compatibility requirements of the radio station.The design of this paper simplifies the structure of the radio hardware,and promotes the compatibility between various stations,which has important application value.
