Intel enhances MMX for better real-time processing
Tom Foremski
Intel has begun releasing details of a new version of its MMX instruction set, which handles DSP type multimedia functions in software. The enhanced MMX2 instruction set is designed to address some of the limitations of the existing MMX instructions.
The additional instructions focus on improving 3D graphics displays and video decoding. MMX microprocessors will also be better at context switching in which the microprocessor switches from floating point to MMX processing. Advanced Micro Devices’ K6 already has faster context switching.
Pentium II microprocessors with the improved MMX instruction set should be available in the second half of 1998. By that time, Intel will also offer its I740 graphics coprocessor which will help speed up multimedia functions.
