摘要:
An apparatus and method are described for detecting and correcting instruction fetch errors within a processor core. For example, in one embodiment, an instruction processing apparatus for detecting and recovering from instruction fetch errors comprises, the instruction processing apparatus performing the operations of: detecting an error associated with an instruction in response to an instruction fetch operation; and determining if the instruction is from a speculative access, wherein if the instruction is not from a speculative access, then responsively performing one or more operations to ensure that the error does not corrupt an architectural state of the processor core.
