Help me select FPGA for a LED full color video display

[psergiu]

Hello ,
I am trying to build a led full color display.

For my project i was thinking of using a FPGA as a controller:
PC (video source with VGA converter)->data from the vga converter is passed into the fpga (in a buffer module which retrieves the RGB data )-> the data is passed to a RAM memory-> form where is fetched by the LEDassign module which sets the color of each led.
I have not yet started my project(is still theoretical)
PROBLEMS:
which fpga should i choose
how can i pass the data from one fpga to the other(Ethernet?? how??)
how does the actual load of the fpga takes place

Re: led video display

1)choice of FPGA can b made by keeping in mind the size of ur hardware. i.e. after u have desighned the logic for your circuit then u will choose the FPGA


2)FPGA can be used as a controller........... so directly communicate with the other FPGA using buffers by making controller parts in FPGA

3)questionn is not clear

led video display

1. Altera/Xilinx/ Lattice, also you wiull need video buffer to store your frame(s) FPGA does not have enough internal memory use SDRAM chiaper and less pins

using LVDS check Altera web site for app notes

depends on FPGA can serial can be paralle configuration

Also you will need ADC for converting your video to digital form

For LED use SMD tricollor LED looks nice

Please pay attention to LED drivers, and power supplies
