Fast to transfer large amount of data from NIOS to FPGA ??

Question

Hi,
I'm searching a method to transfer large amount of data (350 bytes) from NIOS processor to FPGA via Avalon Interface. The board I'm using is DE0-Nano from Altera, therefore, I'm trying to implement via the software tool Altera DSP Builder by using the Altera DSP Builder's blockset. By this time, I've figured out a way using the Avalon-MM Slave Block but each time I could only transfer 4 bytes, so I have to transfer about 88 times to get the full data package. How can I implement this in a more concise way ?

Hi,I think you can use Avalon-MM Slave Bursting Type. Check this https://www.intel.com/content/www/us/en/docs/programmable/683667/21-1/avalon-mm-slave-interfaces.htmlAvalon® Interface Specifications - https://www.intel.com/content/www/us/en/docs/programmable/683091/20-1/burst-transfers.htmlBest Regards,Shengp/s: If any answer from community or Intel support are helpful, please feel free to mark as solution and give Kudos.
