    • 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.
    • 描述处理器操作方法和集成电路。 根据一个实施例,集成电路包括被配置为执行第一应用并且在执行第一应用时冗余地执行第二应用的处理器,所述第一应用与第二应用不同。 根据另一个实施例,处理器操作方法包括使用具有多个处理器核的处理器来接收执行应用的请求。 所述方法还包括:响应于所述接收,确定所述应用是否应该被冗余地执行或非冗余地执行,如果所述确定包括确定所述应用应该被执行,则非冗余地执行所述应用的多个处理器核心, 冗余地并冗余地执行应用程序,如果确定包括确定该应用程序应该被冗余执行,则使用多个的两个或多个处理器核心。
