ABSTRACT:
A system and method for tracking early exceptions in a microprocessor system by inserting specially encoded exception messages into an instruction buffer when it is determined that a fetched instruction will generate an exception if executed. A retire unit removes executed instructions from the instruction buffer in program order, and, upon removal of an exception message, signals an appropriate exception.
