Energy-efficient SIMD Processors for Multimedia Applications

There is increasing demand for low-power processors capable of decoding and encoding streaming media in mobile devices such as cellphones and PDAs. In this talk I shall explore some of the architectural options for energy efficient media processors and illustrate the potential for SIMD parallelism with a novel SIMD media processor developed recently in collaboration with a UK microprocessor IP company. This architecture brings together a high-performance SIMD execution pipeline with a decoupled instruction issue model and a media-aware DMA device. During the talk I'll give examples of how media algorithms are mapped onto the SIMD instruction set, and how the introduction of application-specific extensions can improve both performance and energy-efficiency. I shall present performance figures and compare the resulting physical characteristics of the processor with other recently introduced SIMD media processors.
