ABSTRACT:
A system and method provides hardware support for fast software emulation of unimplemented instructions using issue trap logic that determines the instruction type and parameter fields of an unimplemented instruction when an exception is triggered and uses the fields to branch directly to emulation code specific to an unimplemented instruction having the determined instruction type and parameter fields.
