A fixed-point multimedia co-processor with 50Mvertices/s programmable SIMD vertex shader for mobile applications

A fixed-point multimedia co-processor is designed and integrated into an ARM-10 based mobile graphics processor for portable 2-D and 3-D multimedia applications. The user-programmable SIMD vertex shader with ARM-10 co-processor architecture realizes advanced 3-D graphics algorithms and various multimedia functions. Different from conventional ARM co-processor architecture, the multimedia co-processor implements dual operations, by which parallel and streaming multimedia processing is enabled in mobile applications. For low power consumption, fixed-point SIMD Datapath is designed with instruction-wise clock gating. The co-processor takes 10.2mm(2) in 0.18 mu m 6-metal standard CMOS logic process and achieves 50Mvertices/s graphics performance with 75.4mW power consumption.
