writing to custom PL IP registers from PS

Former Member

Hi guys i got 2 questions..

i implemented two custom IPs in the PL fabric but i need to transfer values/signals to them from the PS (baremetal C).

first i have an "enable" signal which is an input to my PL implementation, is there anywhere to drive this signal from the PS? im planning to use the AXI for this purpose. (1 bit of AXI) is there any other methods??

The other thing i have is parameters defined in the PL, or registers. the values of these registers will control FIFO (custom fifos) and queue sizes tha i created. Is there a way to write to those registers from the PS?

Many thanks guys!

    Thank you for the replies

    My data bandwidth is around 16+ Mbps
    I didnt know about the CIP, i will check it out!

    Basically the register values are for PL IP configuration purposes only, so if it takes some time to write to them its okay.
    Thought i did mean registers that i implemented. (basically i have a shift register of 16 bits which i want to write to as its value reflects some behaviour of my implementation).
