Accelerating mobile video applications using Intel/sup /spl reg// Wireless MMX/spl trade/ technology

Demand for mobile video applications is growing today in wireless handheld platforms. Intel/sup /spl reg// Wireless MMX/spl trade/ technology has been designed to accelerate video applications by using single instruction multiple data (SIMD) techniques to expose and accelerate the data parallelism inherent in video processing. Intel Wireless MMX technology is a 64-bit SIMD coprocessor of the Intel XScale/spl trade/ microarchitecture which is optimized for low-power handheld applications. The paper provides an overview of the Wireless MMX technology architecture, its instruction set, pipeline organization and functional units. It also provides analysis of the features of the architecture that specifically enhance the video performance. Initial measured performance results are also provided.
