Functional Overview

This chapter contains functional descriptions of each major logic block on
the VXIpc 870 Series.

VXIpc 870 Series Functional Description

The VXIpc 870 Series is a VXIbus embedded controller in a C-size form
factor. It includes many high-performance peripherals that normally
require add-in cards on desktop PCs. In addition, it has a VXIbus interface
that is controlled from the PCI local bus, providing extremely high
performance and reliability.

Figure 5-1 is a functional block diagram of the VXIpc 870 Series.
Following the diagram is a description of each logic block shown.
