SW Resource Prioritization

Resource Prioritization enables an OS to specify the priority of a thread to the processor P/LP E core. The processor P/LP E core may use the OS specified thread priority to optimize allocation of shared hardware resources based on priority. The processor decision on how to optimally allocate resources will be based on various system constraints in addition to the priority of other actively running threads. For example, a thread with higher priority may be allocated more of a resource when compared to a thread that has been tagged with a lower priority.

The following are key features of Resource Prioritization:

  • Thread tagging interface to indicate priority of a thread
  • Fixed 4 levels of priority
    • Priority 0 = Highest Priority
    • Priority 1 = Lower Priority than Priority 0
    • Priority 2 = Lower Priority than Priority 1
    • Priority 3 = Lowest Priority
  • Priority Based Resource Allocation of shared hardware resources
