VIODC Overview
Introduction
The Video Input and Output Daughter Card (VIODC) is a standard video interface card for
Xilinx development platforms. It is compatible with ML401, ML402, and ML403 boards
and other future Xilinx development platforms. The VIODC is shown in
mounted on a ML402 platform. The VIODC provides access to high definition (HD) and
standard definition (SD) video streams, as well as computer graphics video interfaces,
such as VGA over DVI and SDI interfaces.
shows a block diagram of the VIODC card. The VIODC consists of a number of
video interface ICs connected to a Xilinx XCV2P7 FPGA. The VIODC is a daughter card
which plugs onto a Xilinx ML40x FPGA platform via the XGI connector. The XGI connector
provides a 64-signal bus between the ML40
x
and the VIODC. Collectively these signals are
called the VIOBUS in this document.
