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: Provided are an apparatus and a method for effectively managing threads diverged by a conditional branch based on Single Instruction Multiple-based Data (SIMD). The apparatus includes: a plurality of Front End Units (FEUs) configured to fetch, for execution by SIMD lanes, instructions of thread groups of a program flow; and a controller configured to schedule a thread group based on SIMD lane availability information, activate an FEU of the plurality of FEUs, and control the activated FEU to fetch an instruction for processing the scheduled thread group.

Abstract translation: 提供了一种用于有效地管理由基于单指令多基数据（SIMD）的条件分支发散的线程的装置和方法。 该装置包括：多个前端单元（FEU），被配置为提取SIMD通道执行程序流的线程组的指令; 以及控制器，被配置为基于SIMD通道可用性信息调度线程组，激活所述多个FE的FEU，并且控制所激活的FEU以获取用于处理所调度的线程组的指令。
