Abstract
A micro processor emulator in which an SMM flag is set whenever a processor being emulated enters system management mode (SMM) mode, a diminished power mode, and is reset when the processor leaves SMM mode. Events, such as branch instructions, that are recorded in a trace memory while the processor is in SMM mode (when the SMM flag is set) are recorded as a trace frame comprised of a trace word and an associated in system management mode (IN.sub.-- SMM) trace bit. When a user evokes interrogation mode of the emulator, the IN.sub.-- SMM trace bit is used to calculate correct physical addresses for disassembly of the recorded trace information.
