AXI bus input-output on PYNQ-Z2

I am doing an implementation of a SHA256 hashing algorithm on the PYNQ board. I came up with some issues regarding the usage of the PYNQ library for IO between the SHA256 IP overlay and the PS on the board.

 

Block design of overlayBlock design of overlay

I would like to send and recieve data between the PS and the SHA256 IP.

There are a few questions on my mind.

1.Is this the proper implementation?

2. How do I do data transfer between the PS and SHA256 IP using PYNQ libraries(if any)?

Apparantly behavioral simulation of the IP shows proper results.
