128-bit 2D Graphics Engine

The PN800 North Bridge's advanced 128-bit 2D graphics engine delivers high-speed 2D acceleration for productivity

applications. The enhanced 2D architecture with direct access frame buffer capability optimizes UMA performance and

provides acceleration of all color depths.

MPEG Playback

The PN800 North Bridge provides the ideal architecture for high quality MPEG-2 based video applications. For MPEG

video playback, the integrated video engine offloads the CPU by performing planar-to-packed format conversion and

motion video compensation tasks, while its enhanced scaling algorithm delivers incredible full-screen video playback.

Video Capture

The PN800 North Bridge implements an optional Video Capture Port which supports various video capture standards,

including ITU-R BT656, VIP 1.1 and VIP 2.0 and is compliant with the most common video capture formats: 16 / 32-

bit RGB and YUV422. With the integrated video capture feature, the PN800 can provide high performance video

effects for video capturing and playback.

LCD, DVI Monitor and TV Output Display Support

The PN800 provides three “Digital Video Port” interfaces: FPDP, GDVP1 and DVP0. The Flat Panel Display Port

(FPDP) implements a 24-bit / dual 12-bit interface which is designed to drive a Flat Panel Display via an external

LVDS transmitter chip (such as the VIA VT1631, NSC DS90C387R or Chrontel CH7017). The PN800 can be

connected to the external LVDS transmitter chip in either 24-bit or dual-12-bit modes. A wide variety of LCD panels

are supported including VGA, SVGA, XGA, SXGA+ and up to UXGA-resolution TFT color panels, in either SDR (1
