The board contains five subsystems: IO(PCI Bus), Memory, Bus Interface, FireHose
Interface, and Clock Generation. Four of these subsystems: the IO(PCI Bus),
Memory, Bus Interface and internal board interface subsystems include ASICs. The
Clock subsystem distributes and generate clocks for the ASICs and PCI Bus
Interfaces on the board.
