MMX (instruction set)
The Pentium processor with MMX technology boasts three primary architectural design enhancements as compared to its predecessor, the Pentium processor:
- New Instructions: powerful new instructions as compared to the Pentium processor to manipulate and process video, audio and graphical data efficiently.
- SIMD: the Single Instruction Multiple Data (SIMD) process allows the chip to reduce multiple compute-intensive loops common with video, audio, graphics and animation. It's like a drill sergeant telling an entire platoon, "About face," rather than commanding each individual soldier one at a time.
- More Cache: doubled on-chip cache size (as compared to the Pentium processor) to 32K, reducing the number of times the processor has to access slower, off-chip memory areas for information.
Since the Pentium processor with MMX technology's debut in January 1997, Intel has released an even more powerful microprocessor, the Pentium II processor.
