A 172.6mW 43.8GFLOPS energy-efficient scalable eight-core 3D graphics processor is designed and implemented for mobile multimedia applications. It is fabricated in 65nm CMOS technology with core size of 7.56mm2. The buffer bridged scheduler, energy efficient transaction technique and approximated rendering scheme are proposed to efficiently utilize energy to deliver excessive graphics rendering performance of 1.2Gvertices/s and 2.4Gpixels/s for 3D graphics applications. Moreover, configurable filtering unit (CFU) is also employed for accelerating image processing. Compared with state-of-the-art image signal processors (ISPs), 1.1 times to 7.2 times performance can be achieved by the proposed mobile graphics processor with CFU. |
