PNX1300/01/02/11 Data Book
• A high-performance bus and memory system that
• A flexible external bus interface.
Figure 2-1
a PNX1300 system consists of the PNX1300 micropro-
cessor itself, external synchronous DRAM (SDRAM),
and the external circuitry needed to interface to incoming
and/or outgoing video and audio data streams and com-
munication lines. PNX1300’s external peripheral bus can
gluelessly interface to PC! 2.1 components and/or 8-bit
microprocessor peripherals.
Figure 2-2
PNX1300 system. A video input stream might come di-
rectly from a CCIR 656-compliant video camera chip in
YUV 4:2:2 format through a glueless interface in this
case. An analog camera can be connected via a CCIR
656 interface chip (such as the Philips SAA7113H).
PNX1300 outputs a CCIR656 video stream to drive a
dedicated video monitor. Stereo audio input and up to 8-
channel audio output require only low-cost external ADC
and DAC. The operation of the video and audio interface
units is highly customizable through programmable pa-
rameters.

PNX1300 requires few supporting components.
The glueless PCI interface allows the PNX1300 to dis-
play video in a host PC’s video card. The Image Copro-
cessor (ICP) provides display support for live video input
an arbitrary number of arbitrarily overlapped windows.
