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 .
