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 translation: 提供了一种用于翻译多线程程序代码的方法和装置。 该方法包括：根据同步点将多线程程序代码划分为多个语句; 通过基于所述多个语句中包括的指令的数目组合一个或多个相邻语句来生成至少一个循环组; 扩展或重命名所述多个语句中的每一个中的变量，使得包括在所述至少一个循环组中的每个语句相对于不同工作组的工作项执行; 并且分别将生成的至少一个循环组中的每一个包围工件项聚合循环。

Abstract: A fusing unit and an image forming apparatus including the same, and method are provided. The fusing unit senses an error such as local overheating in a surface heater, which uniformly emits heat throughout the surface of a belt member. The fusing unit includes a heating member with a pattern to heat a recording medium, a power supply to supply power to the heating member, a pressing member to transmit rotational force to the heating member while in contact with the heating member and to apply pressure to the recording medium, a driver to rotatably drive the pressing member, a pattern sensor to sense the pattern, and a controller to determine whether there is an error in the rotation of the heating member, based on an output from the pattern sensor.

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: 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.
