Zybo digital filter

[0928090]

Hello,

i currently work on a project to make a digital filter with the ZYBO board. I use the ZYNQ XADC for input data and an external PMOD DA2 for output. The filter should only be operating in the FPGA and only the coefficients should be calculated and loaded by the ARM CPU. So the signal data comes from the adc to the digital filter IP and then goes to the dac, all per AXI Stream interface. My problem is that i dont find any SPI IPs who are compatible with AXI Stream. Does anyone have any suggestions?

Hello 0928090,

I found this IP that seems to meet your needs.

Hello and thanks for your answer.

I know this IP but i dont know how i could use it for my needs since according to the datasheet it doesn't support AXI Stream, only AXI Memory Mapped interface.
The datasheet also mentioned in the section "XIP mode" that the AXI Memory Mapped interface is for reading operations only.
Since i only want to write data from a stream to the SPI module i think it doesn't meet my needs, but maybe i am wrong.

Thanks for your help.

Hi 0928090,

You are correct. I found this page that lists all of the AXI Stream IP's. Take a look and see if you find what you are looking for. If not I would recommend posting on the Xilinx forums, since this is about the Xilinx software and not about the board.
