TwisterT＇s advanced 128-bit 2D graphics engine delivers high-speed 2D acceleration for productivity applications. Several enhancements have been made to the 2D architecture to optimize SMA performance and to provide acceleration in all color depths.
TwisterT supports a wide variety of DSTN or TFT panels through a 36-bit CMOS interface. This includes support for VGA, SVGA, XGA, and SXGA+ TFT color panels with 9-bit, 12-bit, 18-bit (both 1 pixel/clock and 2 pixels/clock), and 24-bit CMOS interfaces. Enhanced STN hardware with 256 gray scale support and advanced frame rate control to provide up to
16.7million colors. In addition, the integrated 2-channel LVDS interface can support 18-bit color panels. All resolutions are supported up to SXGA+ (1400x1050). The integrated ZV-Port allows display of video from an external source.
1.6.3VIA VT82C686B South Bridge
The VT82C686B PSIPC (PCI Super-I/O Integrated Peripheral Controller) is a high integration, high performance, power-efficient, and high compatibility device that supports Intel and non-Intel based processor to PCI bus bridge functionality to make a complete Microsoft PC99-compliant PCI/ISA system. In addition to complete ISA extension bus functionality, the VT82C686B includes standard intelligent peripheral controllers:
•Master mode enhanced IDE controller with dual channel DMA engine and interlaced dual channel commands. Dedicated FIFO coupled with scatter and gather master mode operation allows high performance transfers between PCI and IDE devices. In addition to standard PIO and DMA mode operation, the VT82C686B also supports the UltraDMA-33 standard to allow reliable data transfer rates up to 33MB/sec throughput. The VT82C686B also supports the UltraDMA-66 and UltraDMA-100 (ATA-100) standards. The IDE controller is SFF-8038I v1.0 and Microsoft Windows-family compliant.
•Universal Serial Bus controller that is USB v1.1 and Universal HCI v1.1 compliant. The VT82C686B includes the root hub with four function ports with integrated physical layer transceivers. The USB controller allows hot plug and play and isochronous peripherals to be inserted into the system with universal driver support. The controller also implements legacy keyboard and mouse support so that legacy software can run transparently in a non-USB-aware operating system environment.
•Keyboard controller with PS2 mouse support.
