MMX is a Pentium microprocessor from Intel that is designed to run faster when playing multimedia applications. According to Intel, a PC with an MMX microprocessor runs a multimedia application up to 60% faster than one with a microprocessor having the same clock speed but without MMX. In addition, an MMX microprocessor runs other applications about 10% faster.
The MMX technology consists of three improvements over the non-MMX Pentium microprocessor:
- 57 new microprocessor instructions have been added that are designed to handle video, audio, and graphical data more efficiently.
- A new process, Single Instruction Multiple Data ( SIMD ), makes it possible for one instruction to perform the same operation on multiple data items.
- The memory cache on the microprocessor has increased to 32 thousand bytes, meaning fewer accesses to memory that is off the microprocessor.
