The nine examples used in this experiment is show n in Fig.3.Among them，the program gTrn，M an，M ap，Venus，Cow and Emboss are for static target testing，the program Little Jet，lesson6 and Dolphins are for dynamic target testing.Table 3 show s the number of pixels and the number of vertices in nine examples.The number of pixels and the number of vertices are obtained from the cycle-accurate performance simulation platform.The ratio of the pixel numbers and vertex numbers reflects the load of the vertex shader and the pixel shader.Fig.4 show s the comparison of the pow er consumption results of the vertex shader.Fig.5 show s the comparison of the pow er consumption of the pixel shader.As can be seen from the figure，in the absence of low-pow er technology，w hether it is vertex shaders or pixel shaders，the pow er consumption that each test program consumes changes little.With low-pow er programming technology，the pow er consumption changes greatly，at this time the pow er consumption is mainly related to the w orkload of vertex shader and pixel shader.
