Abstract: A swizzle pattern generator is provided to reduce an overhead due to execution of a swizzle instruction in vector processing. The swizzle pattern generator is configured to provide swizzle patterns with respect to data sets of at least one vector register or vector processing unit. The swizzle pattern generator may be reconfigurable to generate various swizzle patterns for different vector operations.

Abstract: A method and apparatus for translating a multithread program code are provided. The method includes: dividing a multithread program code into a plurality of statements according to a synchronization point; generating at least one loop group by combining one or more adjacent statements based on a number of instructions included in the plurality of statements; expanding or renaming variables in each of the plurality of statements so that each statement included in the at least one loop group is executed with respect to a work item of a different work group; and enclosing each of the generated at least one loop group respectively with a work item coalescing loop.

Abstract: A processor device includes a scheduler and a performance counter. The scheduler schedules commands of a first command set and commands of a second command set for a functional unit. A performance counter counts numbers of times where events of interest respectively occur while the functional unit processes first operations directed by the first command set and second operations directed by the second command set. The commands of the first command set are repeatedly scheduled such that the numbers of times for all the events of interest are counted with regard to the first operations. The commands of the second command set are scheduled after the numbers of times for all the events of interest are counted with regard to the first operations.

Abstract: A multi-core computing device includes a control core group having first low-level control cores and a processing core group. The control core group allocates work groups for executing an Open Computing Language (OpenCL) kernel to the first low-level control cores and first processing cores among the processing core group. The processing core group performs processing of the work groups allocated by the control core group outputs results of the processing. The control cores are hierarchically grouped.
