ABSTRACT:
A development system includes two processors which can each act as the central processing unit of the development system. Control is passed between the processors via a system management mode (SMM) interrupt under the X86 architecture. In one embodiment, one of the processor is a processor to be emulated and the other processor is an emulating processor. Since the emulating processor runs at a much slower clock speed than the emulated processor, an application program can be run by the emulating processor until a region of interest is reached. The control of the application program can then be transferred by the SMM interrupt to the emulated processor. This arrangement allows a new compatible microprocessor to be efficiently developed using a hardware emulation system.
