The descriptions in the following sections make reference to the functional 
block diagram supplied in 

. 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

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 

.
