Look at the SGDMA controller. I believe you can configure it to DMA from an Avalon-MM source (memory) to an Avalon-ST stream, and from an Avalon-ST stream to Avalon-MM memory. You would use the DMA controller as your Avalon-ST source and Avalon-ST sink, and connect your convolution filter to those ports.

If you have questions about the SGDMA controller, post a new thread, I haven't used it, so cannot help with it.

Cheers,
