Abstract:

As for the technical problems of interrupt handling, and the I/O port access conflicts in designing programmable device simulation systems, we apply t   he scheme of virtual machine to PDSS and finish the design of a PDSS virtual machine. On the basis of introducing its structure and functional modules,     the paper detailedly discusses two technical problems of memory management and virtual interrupt handling in virtual machine design and gives a specific method, which excellently solves the problem of programmable device simulation.

Key words: （simulation system, virtual machine;virtual memory management;virtual interrupt）
