Question about adding custom module (in Verilog)

Former Member

Hi all,

I've created a processor according to the online speedway training videos. Now, I would like to add my DSP module (in Verilog) to the embedded system so that the processor can control the DSP module.

My question is how to put the processor and my DSP module (in verilog) together? Do I create a top level (in Verilog) module and add both processor and DSP module into it? And then wire up the processor and DSP module like the normal way of designing top level module in Verilog?

Are there any tutorial about this?

Cheers,
kbkien

    Hi

    The fact that your module is written in Verilog is not important.

    If the peripheral already exists and has an AXI connection which conforms to the standard used by XPS, then you can import it into XPS using the Create/Import Peripheral wizard and connect it to the processing system there.

    If the peripheral doesn't exist or doesn't use AXI as it's interface then you can create a wrapper for it using the Create/Import peripheral wizard.

    There are quite a few examples, ZynqGeek's blog post on the subject is quite easy to follow (link below).  All you need to do to change it to Verilog is check a box in the wizard.
