6.4 CONTROLLER
6.4.1 OVERVIEW
The controller uses GW (Grand Workware) architecture. GW architecture is also
referred to as “Next Generation” architcture.
1. CPU : QED RM7000 (300 MHz)
2. COMIC (Color Model IC) : Next Generation (GW) architecture ASIC. This uses
a 120 MHz bus (64 bit) for interfacing with CPU and memory. It controls the
interface with the CPU and controls the following functions: memory, local bus,
interrupts, PCI bus, video data, HDD, network, operation panel, IEEE1284, and
image processing.
3. KLAVIER: This ASIC is the interface with the engine controller board.
4. SDRAM DIMM (2 slots) : 64 MB SDRAM (resident), expandable up to 384 MB
with a 64 MB, 128 MB, or 256 MB SDRAM
5. Flash ROM : 8 MB flash ROM programmed for the system and network
applications; 4 MB mask ROM for storing internal printer fonts
6. ROM DIMM (2 slots) : The DIMM installed in the machine includes 8 MB flash
ROM programmed for system, printer, PCL5c, PS3, and RPCS applications.
The remaining DIMM slot is used for the Bluetooth Option.
