What is MMX Technology
MMX Technology: MMX (Multimedia extensions) technology adds 57 new instructions to instruction set of Pentium - 4 microprocessors. MMX technology also introduces new general purpose instructions. New MMX instructions are designed for application like motion video, combined graphics with imageprocessing, video, audio synthesis, speech synthesis and compression, video conferencing, telephony, 2D and 3D graphics. These new instructions operate in parallel with other operations as instruction for the arithmetic coprocessor. MMX architecture introduces new packed data types. Data types are eight packed, consecutive 8-bit bytes; four packed, consecutive 16-bit words; and two packed, consecutive 32-bit double words.
