1.3.6
Video Display Subsystem
The initial offering of the TM5000 Series Notebook Family contains a
built-in TSTN (Triple Super Twist Nematic) active matrix color LCD with
CCFT (Cold Cathode Fluorescent Tube). The LCD has a VGA compatible
resolution of 640 by 480 pixels. All members of the TM5000 family support
simultaneous LCD and external VGA display at 640 x 480 resolution.
At the heart of the notebook’s video subsystem is a powerful video engine,
the Cirrus Logic CL-GD7542 GUI-accelerated Super VGA LCD Controller
with MotionVideo
tm
implemented on the Main Board. Features of this video
engine include:
•
32-bit Block Transfer Engine with GUI Acceleration
•
640 x 480 LCD support
•
True-color capability
•
Motion-Video architecture with live video overlay
The video subsystem includes a 2 MB RAM memory, 32-bit DRAM bus, and
separate display and memory clocks. An additional frame buffer/accelerator
DRAM increases the available memory band width for CPU accesses. The
video section also uses additional levels of write FIFOs, a read cache, page
mode DRAM and full 32-bit bus access to produce a high performance video
system.
1.3.6.1
High Resolution VESA and Extended Modes
The video engine in the notebook is capable of operating at dot clock rates
programmable up to 85 MHz at 5.0 V or 65 MHz at 3.3 V and supports
standard VGA and VESA high-resolution extended modes at refresh rates
up to 75 MHz. The internal palette can be configured as an
industry-standard RAMDAC to provide a palette of 256K colors or
configured for direct color displays of 32K, and 65K colors.
In addition, the video engine supports the following Super VGA modes:
•
640 x 480 with up to 65K colors on LCD and CRT
•
800 x 600 with up to 65K colors on LCD and CRT
•
1024 x 768 with up to 256 colors on CRT
•
1280 x 1024 with up to 256 colors on CRT (interlaced)
1.3.7
Sound Subsystem
All members of the TM5000 series include a Jazz 16 Sound chip set which
supports stereo digital recording and playback, microphone and line input,
automatic gain control, 20-voice FM music synthesizer, 44.1 Khz audio
recording and playback, built-in file compression/decompression, and
built-in power amplifier with volume control. Jazz 16 software supplied with
the system provides for computer control of all sound features.
