FIR compiler

Hello!

I am using Vivado 2018.3 and Minized Board with Zynq 7z010.

I am trying to use the FIR compiler without the AXI interface. Only by generating the signals for tvalid and tready and it's not working.

If there's a project/tutorial/documentation for that?

Re: FIR compiler

Hi

You can use the multiple and add blocks in Vivado and implement the equation in difference of you filter without an AXI interface. In sysgen you can implement the FIR Compiler block, see the attached file.

If this work to you let me know.

回复: FIR compiler

The FIR Compiler only provides the AXI4 stream interface, it does not provide any other interface. So if you want to use FIR without AXI interface, one way is to build your own FIR filter in HDL or SysGen.

Re: FIR compiler

Hello,

Thanks a lot for the advice. Know I am building the filter using, multiplicator, dff and adder.
I tried to use sysgen but I can't find a free version.  Do you know where I can find the free version?

Re: FIR compiler

see https://www.xilinx.com/products/design-tools/vivado/vivado-webpack.html, Vivado webpack has sysegn which allows you to use for 30 days for free.

Re: FIR compiler

Free version of SysGen will not allow you to generate the IP for the design.

May be you can use Vivado HLS for generating the IP.
Also, HLS document 'UG871 (chapter 11)' contains an example of FIR filter.

Re: FIR compiler

@dragos_dascalu96,

If you want filtering code, but without the AXI interface, you can check out the filters in this project: https://github.com/ZipCPU/dspfilters.  Perhaps those might get  you closer to what you need?
