Abstract:
In an embodiment, a processor includes a plurality of cores. Each core may include strand logic to, for each strand of a plurality of strands, fetch an instruction group uniquely associated with the strand, wherein the instruction group is one of a plurality of instruction groups, wherein the plurality of instruction groups is obtained by dividing instructions of an application program according to instruction criticality. The strand logic may also be to retire the instruction group in an original order of the application program. Other embodiments are described and claimed.
Abstract:
A method and apparatus are described for efficient memory renaming prediction using virtual registers. For example, one embodiment of an apparatus comprises: a memory execution unit (MEU) to perform store and load operations to store data to memory and load data from memory, respectively; a plurality of memory rename (MRN) registers assigned to store and load operations, each MRN register to store data associated with a store operation so that the data is available for a subsequent load operation; and at least one MRN predictor comprising a data structure to allocate virtual memory rename (VMRN) registers to each of the MRN registers, the MRN predictor to query the data structure in response to a load and/or store operation using a value identifying the MRN register assigned to the load and/or store operation, respectively, to determine a current VMRN register associated with the load and/or store operation.
