Chapter 1 – Introduction
The XVME-653 VMEbus Pentium
®
MMX™ PC-compatible VMEbus processor module
and the XVME-658 VMEbus AMD-K6
®
-2 PC-compatible VMEbus processor module
are designed to combine the high performance and ruggedized packaging of the VMEbus
with the broad application software base of the IBM PC standard. These modules inte-
grate the latest processor and chipset technology.
At the core of the XVME-653 is an Intel
®
233 MHz Pentium CPU with MMX technol-
ogy. This generation of Pentium processors features enhanced multimedia instructions,
larger level 1 caches, and a 10 to 20 percent performance increase over standard Pentium
processors.
At the core of the XVME-658 is an AMD 333 MHz K6-2 CPU with 3DNOW!™ Tech-
nology. 3DNOW!™ Technology is the first innovation to the x86 processor architecture
that significantly enhances floating-point-intensive three-dimensional (3D) graphics per-
formance. The AMD-K6-2 system can provide performance comparable to the many of
the Pentium II systems on the market today.
