The mobile Pentium
®
processor with MMX™ technology on 0.25 micron
extends the mobile Pentium
processor family, providing additional performance for notebook applications. The mobile Pentium processor
with MMX technology on 0.25 micron is compatible with the entire installed base of applications for MS-
DOS*, Windows*, OS/2*, and UNIX* and is one of the major microprocessors to support Intel MMX
technology. Furthermore, the mobile Pentium processor with MMX technology on 0.25 micron has
superscalar architecture which can execute two instructions per clock cycle, and enhanced branch prediction
and separate caches also increase performance. The pipelined floating-point unit delivers workstation level
performance. Separate code and data caches reduce cache conflicts while remaining software transparent.
The mobile Pentium processor with MMX technology on 0.25 micron has 4.5 million transistors, is built on
Intel's 0.25 micron manufacturing process technology and has full SL Enhanced power management features
including System Management Mode (SMM) and clock control. The additional SL Enhanced features,
1.8/2.0V core operation along with 2.5V I/O buffer operation, a 320-pin Tape Carrier Package (TCP), and the
Intel mobile module, make the mobile Pentium processor with MMX technology on 0.25 micron ideal for
enabling mobile MMX technology designs. The mobile Pentium processor with MMX technology on 0.25
micron may contain design defects or errors known as errata which may cause the product to deviate from
published specifications. Current characterized errata are available upon request.
