G130/G131 6-78 SM
6.11 PRINTER FUNCTIONS
6.11.1 OVERVIEW
The controller is based on the GW (Grand Work) architecture.
CPU: ICP LV-733 MHz
ASIC:
This is an example of ASICs GW-architecture. It uses a 133 MHz bus to interface
with the CPU and memory. ASIC controls the interface, memory, local bus,
interruption processing, PCI bus, video data, HDD, network, operation panel, host
interface, and image processing.
BIOS ROM: The 1-MB BIOS ROM is for the boot program.
SDRAM DIMM (2 slots):
The controller has 256-MB resident SDRAM. (Either 64, 128 or 256 MB for optional
SDRAM)
NVRAM:
The 32-KB NVRAM stores the engine/controller settings and logs.
Interface Option:
You can install one of the six network components (IEEE1284, IEEE1394, Wireless
LAN, Bluetooth, Gigabit Ethernet, USB Host I/F).
Option: Optional component for all models
