A graphics processing unit may include a register file memory, a processing element (PE) and a load-store unit (LSU). The register file memory includes a plurality of registers. The PE is coupled to the register file memory and processes at least one thread of a vector of threads of a graphical application. Each thread in the vector of threads are processed in a non-stalling manner. The PE storesdata in a first predetermined set of the plurality of registers in the register file memory that has been generated by processing the at least one thread and that is to be routed to a first stallablelogic unit that is external to the PE. The LSU is coupled to the register file memory, and the LSU accesses the data in the first predetermined set of the plurality of registers and routes to the first stallable logic unit. 图形处理单元可以包括寄存器文件存储器、处理元件(PE)和加载存储单元(LSU)。寄存器文件存储器包括多个寄存器。PE耦接到寄存器文件存储器并处理图形应用的线程向量的至少个线程。线程向量中的每个线程是以无拖延方式来处理的。PE在寄存器文件存储器中多个寄存器的第预定集合中存储通过处理至少个线程生成的且要向PE外部的第可拖延逻辑单元路由的数据。LSU耦接到寄存器文件存储器，且LSU访问多个寄存器的第预定集合
