Abstract
An apparatus and method are described for enforcement of reserved bits. For example, one embodiment of a processor comprises: a memory management unit to store a set of bits including a set of reserved bits to a system memory; reserved bit enforcement logic to generate a pseudo-random pattern in the reserved bits and an error correction code over the pseudo-random pattern prior to storing the reserved bits; the memory management unit to load the reserved bits including the pseudo-random pattern and the error correction code; the reserved bit enforcement logic to use the error correction code to determine whether the reserved bits have been modified by software; and if the reserved bits have been modified, then the processor to generate an error condition and if not modified, then the processor to continue normal execution.
