3D图形渲染的能耗估计
Energy consumption estimation for 3D graphics rendering
摘要
Abstract
From the perspective of hardware design and graphics programming,a new energy consumption estimation model of 3D graphics rendering is proposed.Aiming at the energy consumption of the vertex shader and pixel shader in the 3D rendering pipeline,the loads of the vertex shader and the pixel shader which affect the rendering quality are analyzed,and the model of the ratio the number of pixels to the number of vertexes is obtained.At the same time,the energy consumption of vertex shading stages and pixel shading stages are modeled.The model is used to estimate the energy consumption of the benchmark programs,and simulations are performed using the Synopsys VCS simulator and the Power Compiler to obtain the actual energy consumption of these programs.The results show that the geometric mean of the model`s prediction error is less than 3％,which can be used to guide the power consumption analysis and management of graphics hardware and software.关键词
