| 摘要 |
An apparatus for implementing dynamic redundancy for a microprocessor system includes a plurality of microprocessor components, each of which is capable of being selectively placed in a non-operational mode while one or more other of the microprocessor components remain in an operational mode, and then subsequently restored from the non-operational mode back to the operational mode, the spare microprocessor component configured to be switched from the non-operational mode to the operational mode whenever one of the plurality of the microprocessor components is placed in the non-operational mode, and wherein the spare microprocessor component is configured to be switched back to the non-operational mode whenever each of the microprocessor components are in the operational mode; and multiplexing circuitry configured to map the use of the microprocessor components and the spare microprocessor component with respect to the operational mode and the non-operational mode.
