(1,152,000 bits per second).
MMX
A set of 57 multimedia instructions built into Intel’s Pentium microprocessors. MMX-
enabled microprocessors handle many common multimedia operations, such as digital
signal processing (DSP), that are normally handled by a separate sound or video card.
However, only software especially written to call MMX instructions — MMX-enabled
software — can take advantage of the MMX instruction set.
mode

power-saving modes.
