Make connections to existing IP

Former Member

Hello all,

I would like to know the procedure for making connections after adding the existing IP adder /subtraction module.

How do I make connections to the existing IP, especially the adder/subtractor and multiplier modules and how do I communicate with them,  meaning how do I transfer the input store the data, process and get the output and where do I store it. .

Also provide me some additional documentation if any on how do I make those connections.

Thanks and Regards,
Dinesh.

    The adder/subtractor, as an example, is just a 'logic' block that at it's most basic accepts two 15 bit data inputs, controlled by the 'clk' and 'ce' inputs and provides a 15 bit data output value. How you connect it up depends entirely on what you are trying to accomplish.

     

    As an example, you might want to take a 15 bit data value from an A/D connected to the Programmable Logic portion of the Zynq device to one of the data inputs and set the other 15 bit data input to a constant value. This would require you to define a 15 bit input port and define the device pins connected to each of the 15 bit using a constraints file (.xdc). You would connect 'constant' IP to the other 15 bit data input. You would need to use the clock associated with the A/D to clock the adder/subtractor as well as the CE input. If you wanted to read the output of the block directly by the Zynq ARM Processor you could 'route' 15 bit from the PS GPIO to 'EMIO' and connect them directly to the block outputs.

     

    As to how to make these connections I would suggest you review the tutorial resources referenced above.
