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
