    摘要: Processor resource management devices and methods are disclosed. In some implementations, a device includes a processor, a hardware resource, and a resource manager operable to compare a first execution of one or more instructions pursuant to an optimistic resource management policy and a second execution of one or more instructions pursuant to a pessimistic resource management policy, the optimistic resource management policy assuming that less than an optimistic level of at least one error will occur during the first execution, and the pessimistic resource management policy assuming that greater than a pessimistic level of the at least one error will occur during the second execution. Based at least partially on the comparison, the resource manager selects a resource management policy from between the optimistic and pessimistic resource management policies, and associates the selected resource management policy with the one or more instructions.
