| 20080222466 | Meeting point thread characterization - An apparatus associated with identifying a critical thread based on information gathered during meeting point processing is provided. One embodiment of the apparatus may include logic to selectively update meeting point counts for threads upon determining that they have arrived at a meeting point. The embodiment may also include logic to periodically identify which thread in a set of threads is a critical thread. The critical thread may be the slowest thread and criticality may be determined by examining meeting point counts. The embodiment may also include logic to selectively manipulate a configurable attribute of the critical thread and/or core upon which the critical thread will run. | 09-11-2008 |
| 20080244278 | Leakage Power Estimation - Methods and apparatus to provide leakage power estimation are described. In one embodiment, one or more sensed temperature values ( | 10-02-2008 |
| 20080263376 | Frequency and voltage scaling architecture - A method and apparatus for scaling frequency and operating voltage of at least one clock domain of a microprocessor. More particularly, embodiments of the invention relate to techniques to divide a microprocessor into clock domains and control the frequency and operating voltage of each clock domain independently of the others. | 10-23-2008 |
| 20090019219 | Compressing address communications between processors - In one embodiment, the present invention includes a method for determining if data of a memory request by a first agent is in a memory region represented by a region indicator of a region table of the first agent, and transmitting a compressed address for the memory request to other agents of a system if the memory region is represented by the region indicator, otherwise transmitting a full address. Other embodiments are described and claimed. | 01-15-2009 |
| 20090150335 | ACHIEVING COHERENCE BETWEEN DYNAMICALLY OPTIMIZED CODE AND ORIGINAL CODE - An apparatus comprising a first search logic to search for a first entry for a first page containing a first code region in a first data structure to determine whether a first indicator in the first entry is set to a first value; an adder logic to add the first entry to the first data structure, in response to failing to find the first entry in the first data structure; a second search logic to search for a second entry for the first code region in a second data structure, in response to determining that the first indicator is set to the first value, wherein one or more optimized code regions corresponding to the first page from a code cache are to be removed in response to determining that the first page may have been modified, and wherein the first indicator is to be set to a second value. | 06-11-2009 |
| 20090172424 | THREAD MIGRATION TO IMPROVE POWER EFFICIENCY IN A PARALLEL PROCESSING ENVIRONMENT - A method and system to selectively move one or more of a plurality threads which are executing in parallel by a plurality of processing cores. In one embodiment, a thread may be moved from executing in one of the plurality of processing cores to executing in another of the plurality of processing cores, the moving based on a performance characteristic associated with the plurality of threads. In another embodiment of the invention, a power state of the plurality of processing cores may be changed to improve a power efficiency associated with the executing of the multiple threads. | 07-02-2009 |
| 20100115247 | REPLACEMENT POLICY FOR HOT CODE DETECTION - Methods and apparatus relating to a replacement policy for hot code detection are described. In some embodiments, it may be determined which entry amongst a plurality of entries stored in storage unit is to be replaced next. The entries may correspond to hot code and may store age and execution frequency information corresponding to the hot code. Other embodiments are also described and claimed. | 05-06-2010 |
| 20110197195 | THREAD MIGRATION TO IMPROVE POWER EFFICIENCY IN A PARALLEL PROCESSING ENVIRONMENT - A method and system to selectively move one or more of a plurality threads which are executing in parallel by a plurality of processing cores. In one embodiment, a thread may be moved from executing in one of the plurality of processing cores to executing in another of the plurality of processing cores, the moving based on a performance characteristic associated with the plurality of threads. In another embodiment of the invention, a power state of the plurality of processing cores may be changed to improve a power efficiency associated with the executing of the multiple threads. | 08-11-2011 |
