ABSTRACT:
Processor operating methods and integrated circuits are described. According to one embodiment, an integrated circuit includes a processor configured to execute a first application and to redundantly execute a second application while executing the first application, the first application being different from the second application. According to another embodiment, a processor operating method includes receiving a request to execute an application using a processor having a plurality of processor cores. The method also includes, in response to the receiving, determining whether the application should be executed redundantly or non-redundantly, non-redundantly executing the application using one processor core of the plurality if the determining comprises determining that the application should be executed non-redundantly, and redundantly executing the application using two or more processor cores of the plurality if the determining comprises determining that the application should be executed redundantly.
