ABSTRACT:
An embodiment of the invention is a processor for detecting one or more groups of instructions and initiating a processor action upon detecting one or more groups of instructions. The processor includes an instruction unit for fetching and decoding a group of instructions. An instruction register receives the group of instruction having at least one instruction opcode. A control register includes a control word including a control opcode and an action field defining a processor action. An execution unit includes compare logic for comparing the instruction opcode and the control opcode. The execution unit initiates the processor action upon the compare logic detecting a hit between the instruction opcode and the control opcode.
