A preprocessor is functionally inserted between a memory and a processor core. The preprocessor fetches virtual machine instructions, like Java instructions, from the memory and from them it generates native instructions which are supplied to the processor core. In response to a special virtual instruction the preprocessor supplies a native jump to subroutine to the processor core, monitors when the processor core returns from that subroutine and then resumes supplying generated native instructions. The invention also provides for a processor which has a special instruction which calls a subroutine and causes the processor to convert a call context for virtual machine instructions to a call context for a high level language subroutine before making the call. |
