Single Chip Computer Interrupt Technology Research and Application

This paper introduces the application method of how circuit will change the variation of signal level for narrow pulse signal circuit, interrupt signal coding and priority input and revocation, the decoding circuit, the interface circuit of multiple board structure, board structure and multiple address circuit. Based on the analysis of working condition of the multi input signal under the single chip computer, it proposes the use of interrupting technique to improve the stability of the system, and gives the design scheme of software and hardware interrupt system.
