Abstract
An apparatus and method is described herein for replacing faulty core components. General purpose hardware is provided to replace core pipeline components, such as execution units. In the embodiment of execution unit replacement, a proxy unit is provided, such that mapping logic is able to map instruction/operations, which correspond to faulty execution units, to the proxy unit. As a result, the proxy unit is able to receive the operations, send them to general purpose hardware for execution, and subsequently write-back the execution results to a register file; it essentially replaces the defective execution unit allowing a processor with defective units to be sold or continue operation.
