Abstract
An apparatus and method for determining whether data needed for one or more operations is stored in a cache and scheduling the operations for execution based on the determination. For example, one embodiment of a processor comprises: a hierarchy of cache levels for caching data including at least a level 1 (L1) cache; cache occupancy determination logic to determine whether data associated with one or more subsequent operations is stored in one of the cache levels; and scheduling logic to schedule execution of the subsequent operations based on the determination of whether data associated with the subsequent operations is stored in the cache levels.
Claims21
A processor comprising:
- a hierarchy of cache levels for caching data including at least a level 1 (L1) cache;
- cache occupancy determination logic to determine whether data associated with one or more subsequent operations is stored in one of the cache levels;
- and
- scheduling logic to schedule execution of the subsequent operations based on the determination of whether data associated with the subsequent operations is stored in the cache levels.
A method comprising:
- caching data within a hierarchy of cache levels including at least a level 1 (L1) cache;
- determining whether data associated with one or more subsequent operations is stored in one of the cache levels;
- and
- scheduling execution of the subsequent operations based on the determination of whether data associated with the subsequent operations is stored in the cache levels.
A system comprising:
- a memory for storing program code and data;
- a input/output (IO) communication interface for communicating with one or more peripheral devices;
- a network communication interface for communicatively coupling the system to a network;
- and
- a processor comprising:
- a hierarchy of cache levels for caching data including at least a level 1 (L1) cache;
- cache occupancy determination logic to determine whether data associated with one or more subsequent operations is stored in one of the cache levels;
- and
- scheduling logic to schedule execution of the subsequent operations based on the determination of whether data associated with the subsequent operations is stored in the cache levels.
