摘要
我们提出了一个152兆瓦的多媒体SoC，具有MPEG4编解码器，H.264解码器，JPEG编解码器和完全可编程的移动应用3D图形。3D图形引擎中的统一着色器提供完全可编程的3D图形，面积减少35%，功耗降低28%。对数照明引擎和专门的照明指令给出9.1Mvertices/s顶点填充率。合并的JPEG/MPEG4编解码器和统一的着色器进一步减少了硅面积，SoC在0.13 mm CMOS逻辑过程中消耗6.4 mm × 6.4 mm。
A 152mW Mobille Multimedia SoC with Fully Programmable 3D Graphics and MPEG4/H.264/JPEG
We present a 152 mW multimedia SoC with MPEG4 codec, H.264 decoder, JPEG codec and fully programmable 3D graphics for mobile applications. The unified shader in 3D graphics engine provides fully programmable 3D graphics with 35% area and 28% power reduction. Logarithmic lighting engine and the specialized lighting instruction give 9.1Mvertices/s vertex fill rate. The merged JPEG/MPEG4 codec and the unified shader reduce the silicon area further and the SoC consumes 6.4 mm times 6.4 mm in 0.13 mum CMOS logic process.
