Hi all, i am currently working on hardware accelerator for a gesture recognition application on DE2i-150.

Hope there is anyone can help me on my problems written below.

I have successfully sent webcam image(640x480x3bytes) to SDRAM in FPGA through PCI express (Avalon Memory mapping). I wish to do some image processing on the image stored in SDRAM. However, i have no idea how to access the data stored in SDRAM. I am using QSYS components now as the PCI ex has to be done there. Is there any Qsys component that can act as SDRAM controller which allows me to access the data ??

Hello Sir,

Do you have already a working example for what you planed to do? I am investigating the same issue and I do not have any clue what i should do.

Thanks
