Abstract
A method for processor error checking including receiving an instruction data, generating a pre-processing parity data based on the instruction data, maintaining the pre-processing parity data, processing the instruction data, generating a post-processing parity data based on the processed instruction data, checking for an error related to processing the instruction data by comparing the post-processing parity data to the pre-processing parity data, and transmitting an error signal that indicates the error related to processing the instruction data occurred if the post-processing parity data does not match the pre-processing parity data, wherein checking for the error related to processing the instruction data is performed without using a duplicate processing circuitry.
