Cell Controller (CC) The cell controller chip co-ordinates memory
between the major components of a cell board -
• memory controllers (DIMMs),
• processors,
• the I/O bus (System Bus Adapter)
- and determines if a request requires communication with another cell
or with the I/O subsystem.
The CC has two interfaces which leave the cell:
• the crossbar interface (XBC link), through which all
communication to other cells flows;
• the System Bus Adapter, which connects the cell to an I/O
subsystem.
See “Cell Components” on page 304 for a block diagram.
