摘　　要：在图形处理芯片GPU的架构设计中,把传统的固定功能部件中的图元设置模块,替换为可编程的着色程序,提出了两个新的着色阶段,称为图元拓扑着色和属性着色。该方法有效地利用了GPU中的流处理器的并行计算能力,同时减少了硬件逻辑部件,有利于芯片流片之后的扩展和维护。作者提出的图元设置着色方法,把传统的硬件逻辑部件,使用可编程的着色程序来替代,有效地利用了流处理器的并行计算能力。In GPU architecture design, the traditional primitive setup module of fixed function units is replaced with programmable shaders, and two new shader stages are proposed, called as primitive topology shader and attribute shader. This method effectively makes use of the parallel computing ability of stream processors in GPU, decreases hardware logic units, and it is more feasible to extend and maintain after GPU chip is tape-out. In this paper, the shader method of primitive elements is proposed, and the traditional hardware logic components are replaced by programmable shaders, so that the parallel computing ability of stream processors is effectively utilized.
