Chapter 1 – Introduction
The XVME-653 VMEbus Pentium
and the XVME-658 VMEbus AMD-K6
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
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.
