VXIpc 870 Series Block Diagram
Processor
The VXIpc 870 Series controllers are based on the Intel Pentium II, Slot 1
architecture. The CPU connects to the motherboard through the 100 MHz
GTL+ bus. Because of this modular design, you can easily upgrade your
VXIpc 870 Series controller with a new CPU. As your application needs
expand or change in the future, you can save money by changing the CPU
as compared to purchasing a brand new controller. The VXIpc 870 Series
controllers are based on Pentium II technology, and deliver 512 KB of
level two cache.
Chip Set and SDRAM
The VXIpc 870 Series uses the latest in Intel Chip Set technology—the
Intel 440BX Chip Set. The 440BX connects the Pentium II to the AGP
port, PCI bus, and the SDRAM. The 440BX uses a 100 MHz bus for the
CPU and SDRAM connections to give the highest performance possible.
The VXIpc 870 Series has three SO-DIMM sockets that can support a
