Continuos Data transfer from HPS to QuartusDCFIFO

Hi,

Typically the h2f lightweight bridge is to perform control and status register accesses to peripherals in the FPGA.

The lightweight HPS-to-FPGA bridge is a fixed 32-bit width connection to the FPGA fabric, since most IP cores implement 32-bit control and status register.

I would recommend you use the h2f bridge for data transfer.

The bridge is intended to be used by masters to perform bursting transfers.

We also have a user guide for DCFIFO user guide here for you reference:

Thanks.

Hello

Thankyou for the reply.

I have both bridges conenctd to Pipeling bridge and in turn connected to avalon Bus. How can I find the exact addressing for accessing the IP(Wher I have DCFIFO intantiated )

And does it solve the problem I mentioned about the data transfer in FIFO as I mentioned in the post above. ?

BR,

Athira

Hi,

I am unsure what you meant by the connection, are you still using the h2f_lw bridge for the data transfer?
