Folks,
I have designed a Core(HDL) which needs to compute on a huge data stored on an external memory. I am planning to use DMA to transfer a chunk of data at a time from SDRAM to on-chip. Here are my questions: 1. Almost all the design examples I saw use nios to facilitate the file transfer operation. Is it not possible to generate the DMA control signals from my core and control/schedule the transfer? Which one will have higher performance? 2. I know how to build such hardware using Qsys/SOPC but I Iack resources on how to develop the SW part, if I end up using nios. Can someone point me to a documentation/link with example programs showing DMA based file transfer? Thanks,- Tags:
