Abstract
Embodiments of an invention for verifying firmware using system memory error check logic are disclosed. In one embodiment, an apparatus includes an execution core, firmware, error check logic, non-volatile memory, comparison logic, and security logic. The error check logic is to generate, for each line of firmware, an error check value. The comparison logic is to compare stored error check values from the non-volatile memory with generated error check values from the error check logic. The security logic is to prevent the execution core from executing the firmware if the comparison logic detects a mismatch between the stored error code values and the generated error code values.
