Abstract: An apparatus and method for executing code are provided. The apparatus includes a memory manager that allocates a stack in memory to store processed data that needs to be retained; a loop generator that divides program code programmed to be processed in parallel into regions based on a barrier function, transforms a region that includes the processed data that needs to be retained in the stack into a first coalescing loop, and transforms a region that uses the processed data stored in the stack into a second coalescing loop such that the transformed program code may be serially processed; and a loop changer that reverses a processing order of the second coalescing loop in comparison to a processing order of the first coalescing loop.

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.
