Abstract:

The paper studies the compiler technology based on virtual machines for the programmable device simulation problem,puts forward a concrete plan of des ign.With the twice-compiling and address-backfill technologies,it builds a perfect and efficient symbol warehouse,which effectively realizes the equival ence exchange from the source code to the destination code.The programmable device compiler（PDC）is designed for programmable device simulation systems s（PDSS）.In PDSS,PDS cooperates with the virtual machine to make the programmable device simulation out of the limitation of a specific processor archi  itecture and independent of the realization of a specific operating system.Thus,it can completely control the whole process from compiling,running to si   mulation.
