VIDEO SUBSYSTEM

The video subsystem, implemented on the system board and on the LCD Panel, controls the display output to both the LED Panel and to the external VGA port.

The video subsystem utilizes the C&T 65548 High Performance Flat Panel / CRT VGA Controller. It also includes 1 MB DRAM memory, 32-bit DRAM bus, and separate display and memory clocks. An additional frame buffer/accelerator DRAM increases the available memory bandwidth for CPU accesses.

Video Chipset Controller

The C&T 65548 initiates a family of 208-pin, high performance for the full-featured note- book that requires the highest graphics performance available. The 65548 achieves superior performance through direct connection to system processor buses up to 32-bits in width. When combined with the CHIPS’ advanced linear acceleration software driver technology, this device exhibits exceptional performance compared with devices of similar architecture. The 65548 also adds a sophisticated 32-bit graphics hardware engine for the Bit Block Transfer (BITBLT), line drawing, hardware cursor, and other functions intensively used in Graphical User Interface (GUIs) such as Microsoft Windows.
