Multimedia and 3DNow! Execution Units
The multimedia and 3DNow! execution units of the
AMD-K6-2E+ processor are designed to accelerate the
performance of software written using the industry-standard
MMX instructions and the new 3DNow! instructions.
Applications that can take advantage of the MMX and 3DNow!
instructions include graphics, video and audio compression and
decompression, speech recognition, and telephony
applications.
3DNow! technology enables fast frame rates on high-resolution
3D-rendered scenes, realistic physical modeling of real-world
environments, sharp and detailed 3D imaging, smooth video
playback, and theater-quality audio.
The AMD-K6-2E+ processor supports five new digital signal
processing (DSP) instructions, developed to enhance the
performance of communications applications, including soft
xDSL modems, MP3 recording, and Dolby Digital and Surround
Sound processing.
