6.10 CONTROLLER
6.10.1 OVERVIEW
The controller uses GW (Grand Work) architecture.
CPU
:
RM7000 (500 MHz)
COMIC (Color Model IC)
:
GW architecture ASIC. It uses a 122 MHz bus (64 bit) for interfacing with CPU and
memory. It controls the interface with the CPU and also controls the following
functions: memory, local bus, interrupts, PCI bus, video data, HDD, network,
operation panel, IEEE1284, and image processing.
SDRAM DIMM (2 slots)
:
64 MB SDRAM (resident), expandable up to 384 MB with a 64 MB, 128 MB, or 256
MB SDRAM.
