Abstract

Abstract: It summarizes all parallel processing ways used in EPA node-device，then analyzes the characteristics of R40008 in the parallel processing，which is a CPU used in EPA node-device.Based on the analyses，a new idea is brought forward that seek the parallel factors in the program to make full use of the parallel design in the R40008 CPU.At last some telling methods are given to optimize program so as to utilize the characteristics of R40008 in the parallel processing.

Key words: real time property, parallel processing, parallel optimize, EPA node-device

摘要： 在对EPA中的并行处理技术总结的基础上，结合EPA节点设计中所用的ARM7结构的R40008 CPU的特点，分析了它在支持并行处理方面的结构设计，提出了进一步挖掘程序设计中的并行因素，充分利用R40008CPU中的并行设计的思想，并给出了针对R40008 CPU的结构，对程序设计进行并行优化的有效方法。
