Overview
The National Instruments VXIpc-77x embedded controllers are
flexible, high-performance controllers in a small, rugged package ideal
for VXI systems. These controllers give you direct control of VXI
registers, memory, interrupts, and triggers while maintaining
compatibility with the scores of software packages and tools available
for general-market desktop PC computers.
NI VXIpc-77x controllers provide the most cost-effective single-
slot VXI embedded control solution available. Table 1 details the
standard VXIpc-77x features.
NI VXIpc-77x controllers use industry-standard VXIplug&play
software, including NI-VXI/NI-VISA and NI-488.2 software. The
NI-VXI/NI-VISA bus interface software is a comprehensive software
package for configuring, programming, and troubleshooting your
VXI system. With NI-VXI/NI-VISA, you can be confident that your
software development will not become obsolete as your needs change
and VXI technology evolves. If you require solid-state storage media
for operation in harsh environments, you can use NI VXIpc-77x
controllers with an internal solid-state flash drive in place of the
internal hard drive.

Hardware
The hardware for a VXIpc-77x controller consists of a single-width
module that fits directly in a C-size VXI mainframe. You can use the
controller in Slot 0 or in non-Slot 0 operation, so you can use several
VXIpc-77x controllers in a system together. VXIpc-77x controllers use
the Intel 815E chipset and a Pentium processor to deliver the maximum
performance and flexibility for your VXI system. Figure 1 shows the
block diagram for VXIpc-77x controllers.
Hardware Architecture
State-of-the-art packaging technology gives VXIpc-77x controllers
the full functionality of a desktop PC in a VXI module. The
controllers required a number of technological advances before NI
could manufacture it, including MITE and MANTIS custom ASICs
for high-performance VXI control, as well as the PCI MITE and
TNT4882 ASIC for GPIB control.
VXIpc-77x controllers have 10/100BaseT Ethernet capability, so you
can quickly and easily integrate the controller into a LAN or WAN.
