一种适用于软件雷达系统的数据流驱动机制

A Dataflow Driven Mechanism for "Soft-Radar" System

针对雷达信号处理各功能模块之间显著的流水性特征 ,结合一个通用的雷达信号处理系统———由清华大学研制的通用高速实时雷达信号处理系统的实验样机DSM(dataflow ,sharedmemoryandmultiplebusinterconnec tion) ,在研究现有静态、动态数据流驱动机制特点的基础上 ,提出了一种新型的适用于软件雷达系统的进程间准动态数据流驱动机制 ,并针对一个雷达信号处理的范例程序说明了编译器数据流驱动表的生成和系统数据流驱动的过程。

A prominent characteristic of radar signal processing is pipelining among different operation blocks. Based on this characteristic a new dataflow driven mechanism for 'soft radar' system is presented. It has been successfully applied in a general radar signal processing system-dataflow, shared memory and multiple bus interconnection (DSM) system. The generation of dataflow tables during the compiling process is studied in detail with a sample program.\;
