1. A method implemented in a computing device, the method comprising: fetching an instruction of an instruction group for execution by a processor having an associated hardware resource; applying a first hardware resource management policy to the fetched instruction of the instruction group to produce a first execution context, the first resource management policy being a pessimistic policy that assumes based on at least one of theoretical information or historical information that the given instruction group will execute in a substantially sub-optimal manner such that greater than a preselected level of at least one error will occur during execution of the given instruction group; receiving a previously selected hardware resource management policy associated with the instruction, the previously selected hardware resource management policy having been selected based on at least one of theoretical information or historical information as being likely to provide a substantially optimum execution of the instruction group when the processor has a predefined execution context; applying the previously selected hardware resource management policy to the associated hardware resource if a predetermined similarity exists between the first execution context of the processor and the predefined execution context when the hardware resource management policy associated with the instruction was selected; and selecting one policy of the previously selected hardware resource management policy and the second hardware resource management policy in response to comparing the first and predefined execution contexts.
