AXI Test IP

This IP-Core is used for testing the AXI communication between PS and PL. The IP-Core calculates \(C=A \cdot B\) with different data types. For all data types except for the float calculation, the input and output values are scalar. The float calculation input and output is a 2x2 matrix.

Use this IP-Core to test read/write operations by AXI between PL and PS using the Hardware Abstraction Layer.
