System and method for implementing dynamic lifetime reliability extension for microprocessor architectures 

A system for implementing dynamic lifetime reliability extension for microprocessor architectures having a plurality of primary resources and a secondary resource pool of one or more secondary resources includes a resource operational mode controller configured to selectively switch of the primary and secondary resources between an operational mode and a non-operational mode, wherein the non-operational mode corresponds to a lifetime extension process; a resource mapper associated with the secondary resource pool and in communication with the resource operational mode controller, configured to map a secondary resource placed into the operational mode to a corresponding primary resource placed into the non-operational mode; and a transaction decoder configured to receive incoming transaction requests and direct the requests to one of a primary resource in the operational mode and a secondary resource in the operational mode, the secondary resource mapped to an associated primary resource placed in the non-operational mode.
