摘要
针对雷达目标识别的特点和要求，文中介绍了一个由六片ＴＭＳ３２０Ｃ５０所构成的实时处理系统．硬件设计上充分利用了ＴＭＳ３２０Ｃ５０本身所带有的资源，构成一个模块化、小体积、低成本的工程实用系统．系统结构由全连接网络和改进型菊花链网络两部分组成．全连接网络用ＴＭＳ３２０Ｃ５０的时分多路（ＴＤＭ）串行口构成，硬件结构极其简易；改进型菊花链网络是以全局存储器为核心的一种可编程互连网络，在优先权仲裁算法上比起传统的菊花链网络有明显的改进．
This paper introduces a real-time system of six TMS320C50s, whichadapts to the behavior and requirement of radar target recognition. The in-houseresources of TMS320C50 are sufficiently utilized in hardware design, and a modular, small-volume and low cost engineering utility system is constructed. The system architecture consists of fully-connected network and modified daisy chain network. The fully-connected network is constructed with the time-division-multiplexed (TDM) serial port of TMS320C50, and has simple hardware configuration.The modified daisy chain network is a programmable interconnection network(PICN) which uses global memory as kernel, and has larger improvement than traditional daisy chain network in priority arbitration algorithm.
