This section introduces the general architecture of the Universe. This
description makes reference to the functional block diagram provided in
Figure 4-1 that follows. Notice that for each of the interfaces, VMEbus and
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. These channels
are:
VME Slave Channel
PCI Bus Slave Channel
DMA Channel
Interrupt Channel
Register Channel
The Architectural Overview is organized into the following sections:
