Functional Description

Architectural Overview

This section introduces the general architecture of the Universe II. This
description makes reference to the functional block diagram provided in
Figure 4-1
PCI bus, there are three functionally distinct modules: master module,
slave module, and interrupt module. These modules are connected to the
different functional channels operating in the Universe II. These channels
are:
The Architectural Overview is organized into the following sections:
