DLPLCRC410EVM

Other Parts Discussed in Thread: DLP9500, DLPLCRC410EVM

Short description: DLP using for high speed video simulation

Case details or comments:

We need to create video simulator on base DLPLCRC410EVM and DLP9500 0.95 module.
We need to generate video film of 1920x1080x1 with frame rate 1000 Hz for 30 seconds, i.e. we need to save 30000 images into DLPLCR410EVM (~7.8GB).
Is DLPLCR410EVM supports such memory volume?
Do you have ready design for such application? Or, may be, you know where we can purchase such design?
Is it possible to change only 1 memory block (72 rows, not full frame) for every frame?

Best regards,

Moisey.

    Hello Moisey,

    Let me answer your second question first.  Yes, you can update just the rows you want to update.  You will need to write vhdl code for the APPS_FPGA to implement loading the rows that you want to change.

    Regarding the "frame rate", if you meant grayscale "frames", then 1000 Hz will be challenging.  If you mean binary patterns (I assume that is what you mean by 1920x1080x1) then this can be done.  What will be needed is add a memory stick to EVM and create a Memory Interface for the APPS_FPGA.  This is IP from Xilinx.

    We do not have a ready design (i.e. VHDL code) for this implementation.  You may want to contact ViALUX as they have platforms designed to do what you are wanting to do.
