图形处理器中双核顶点染色器的设计与实现

Graphics Processor in the Design and Implementation of a Dual Vertex Shader

为了提高图形处理器(graphic processing unit,GPU)中顶点染色器的工作效率,设计了一款改进的可编程双核顶点染色器.它可以同时对来自命令处理器的两条命令进行解析,然后交由PE双核进行处理,这样既可以提高处理器的资源利用率又可以加强处理器的并行执行能力.采用基于FPGA的验证方式,整个双核顶点染色器占用Xilinx V6系列550T型号FPGA芯片硬件资源的7%,最大工作频率能够达到155.411 MHz.

In order to improve the graphics processing unit （graphic processing unit, GPU） vertex shader in the efficiency of work designed a dual-core improved programmable vertex shader. It could also resolve two commands from the command processor and then referred to PE dual-core processing, this way you can improve processor utilization can strengthen the parallel processor implementation capacity. Using FPGA-based authentication methods, the entire vertex shader use 7% Xilinx V6 series 550T FPGA chip hardware resources, the maximum operating frequency can reach 155. 411 MHz.
