Satellite-borne computer CMU simulator design method based on QEMU virtual environment

The invention discloses a satellite-borne computer CMU simulator design method based on a QEMU virtual environment. The method comprises the steps that a, a QEMU system simulator of an SPARC architecture is customized; b) simulating a processor chip of an SPARC V8 architecture, and simulating a real operation environment of satellite-borne embedded software; and c) simulating a CMU simulator peripheral IO controller interface chip, and realizing satellite control subsystem joint debugging. Compared with the prior art, the method has the advantages of better reusability, quickness in construction, stronger controllability, richer debugging and testing means, high performance, flexibility and guarantee of real-time performance, and through simulation of satellite-borne computer CMU hardware equipment, the method can be applied to the field of satellite-borne computer CMU hardware equipment simulation. The real satellite-borne embedded software is loaded in the virtual CPU to simulate the real satellite state, t
