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 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.
The multimedia execution unit can execute MMX instructions
in a single processor clock. All MMX and 3DNow! arithmetic
instructions are pipelined for higher performance. To increase
performance, the processor is designed to simultaneously
decode all MMX and 3DNow! instructions with most other
instructions.
For more information on MMX instructions, see the AMD-K6^®
Processor Multimedia Technology Manual, order #20726. For
more information on 3DNow! instructions, see the 3DNow!™
Technology Manual, order #21928.
