An Efficient Communication Method between Processors in an Embedded Communication System

Due to the different operating clocks between processors in the communication system, the waiting time problem exists in the process of the communication. Generally, time delay is used to adjust the time synchronization in the program code. In the time-based communication system, while either the communication waveform or operating processor is changed, resetting of the time delay is needed. To solve this kind of problem, we will propose a kind of new communication method based on interrupt. The interrupt-based communication method is no more restrained by the change of the processing time. Moreover, it can reduce the troublesome in the program coding. In this paper, the problem which exists because of the different booting times between different processors also gets into the solution. With the using of the proposed communication method in this paper, the stability and the reliability of the communication system can be improved.
