Abstract: An apparatus and method for intelligent power virus protection in a processor. For example, one embodiment of a processor comprises: first circuitry including an instruction fetch circuit to fetch instructions, each instruction comprising an instruction type and an associated width comprising a number of bits associated with source and/or destination operand values associated with the instruction; detection circuitry to detect one or more instructions of a particular type and/or width; evaluation circuitry to evaluate an impact of power virus protection (PVP) circuitry when executing the one or more instructions based on the detected instruction types and/or widths; and control circuitry, based on the evaluation, to configure the PVP circuitry in accordance with the evaluation performed by the evaluation circuitry.
