ABSTRACT:
Described herein is a system and method for providing instruction dependent execution control on a microprocessor device. The system and method utilize instruction match register/execution control register (IMR/ECR) pairs to first identify known problematic instructions and to then alter control of the microprocessor in a preselected manner when processing each problematic instruction. The invention contemplates the use of numerous control options for altering control of the microprocessor.
