Control Interface Module, Continued
The CAC3 utilizes a 32-Bit, 240 MHz microprocessor. The on-board
memory for the CAC3 consists of 128 MB SDRAM, 64 MB NOR Flash,
and 256 MB NAND Flash. The CAC3 also includes an on-board 10/100
Ethernet controller, used for connection to external Ethernet.
CAC3 (continued)
The communication backbone between the CAC and the CIMBase is the
General Purpose Bus (GP Bus). The GP Bus is a 32 bit, 120 MHz
parallel address/data bus with dedicated chip selects and interrupts. In
addition to the GP Bus, the CAC communicates via two serial buses.
One serial bus is dedicated to the serial debug port. The second serial
bus provides the serial communications ports.
