Computational Photography accelerator(Please Help!!!)

Hi,

I'm trying to do an computational photography application that uses FPGA as an accelerator on top of the Zedboard.

Does anyone know how do we input an image file(.ppm file) and put it in the Arm core to process? and how do we display the image file on LCD screen?

I want to extract some part of C code and run it on the FPGA, but I'm not sure how to set up FPGA/DMA transfer in XPS and the C code to handle DMA transfer.

And also, once when FPGA finishes its work, how to set up interrupt?

How to configure FPGA peripherals and how to configure Zedboard system using XPS?

Please help!!!!!

You clearly need to write an application to run on the arm to decode the incoming image file, send via some interface,ethernet usb etc and then you need to write an interface from the processor to the logic, driving an LCD is trivial, if you want me to write it for you send me a specification and ill sent you a quotation for the work ;-)

bobo0507,

This is a good place to get started: http://zedboard.org/content/zedboard-create-planahead-project-embedded-processor

If you have additional bandwidth requirements, investigating the DMA feature will be your next step. This above how-to should get you familiar with the tools and their flow.

After you are done with getting familiar with the tools, start in on this how-to for creating your own peripheral: http://zedboard.org/content/creating-custom-peripheral

Hope that helps!
