WMMX Intrinsic Functions

9/7/2007

The ARM-compliant Intel processors such as the PXA270 processor with Wireless MMX (WMMX) technology have instructions to enable development of optimized multimedia applications. The instructions are implemented as co-processor instructions.

This technology uses the single-instruction, multiple-data (SIMD) technique. By processing data elements in parallel, applications with media-rich bit streams can significantly improve performance by using SIMD instructions.

For complete details of the hardware instructions and intrinsic functions, data types, and registers, see this Web site Intel Wireless MMX Technology Developer Guide.
