Agenda Project goals DVI overview Hardware overview Software overview Implementation Demonstration

Goals To assimilate GIDEL system PROCWizard tool. Learn how DVI and TMDS works Learn how to use PROCStar II Transferring video data we get from the PC Graphic controller to Display through PROCStar II PSDB DVI

Why DVI ?

DVI DVI is accepted standard for transferring serially uncompressed digital data at high speeds between a PC host and a digital display, such as an LCD monitor. DVI enables a video signal to be transferred from a PC source to a digital display in its native digital form, simplifying the way PCs communicate with displays and improving display image quality.

Why DVI? Before DVI was accepted : Plug & Display (P&D)- expensive connector and provided no dual-link option. Digital Flat Panel (DFP)- offered no analog support and no dual-link option or upgrade path for faster speeds.

DVI advantages : Offers analog support through pins on the host side connector,which eliminates the need for a redundant VGA analog conection Available in a dual-link option, providing an upgrade path for even higher-level resolutions Cross compatible with P&D and DFP via mechanical dongle connector

PROCStar II

PSDB PROCStar II and PROCSpark II boards were designed to work with daughterboards. A number of connectors located on the component side of the PROC motherboards enable connecting several daughterboards to these motherboards. These daughter boards are called PSDB. PSDBs can be used for system adaptation and to add logic.

PSDB_DVI PSDB_DVI is a type 1 PSDB. This means that it uses a single connector to connect to the PROC motherboard. On the PROC boards, this connector is located to the left of the target FPGA. PSDB_DVI is designed to provide a Digital Video Interface (DVI) connection to the PROC motherboard via its panel. Therefore, this daughterboard is intended to be placed on location 1 when possible. Nevertheless, it will work properly when connected to any other location on the PROC board.

GiDEL PROCWizard tool GiDEL PROCWizard is a hardware-software integration application that was designed to simplify the project development task. Enables the user to rapidly build a design that may be automatically translated into HDL and C++ code Enables the developer to test and debug the design in the PC environment. PROCWizard main features include :

GiDEL PROCWizard tool
