Block Diagram

The descriptions in the following sections make reference to the functional block diagram supplied in Figure 4-1. Notice that for each interface, VMEbus and PCI bus, there are three functionally distinct modules: master module, slave module, and interrupt module.

These three 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

Functional Description

The functional description is organized into the following sections:

❏VMEbus Interface

❏PCI Bus Interface

❏Interrupter and Interrupt Handler

❏DMA Controller

These sections describe the operation of the Universe in terms of the different modules and channels listed above and illustrated in Figure 4-1.
