The AXI4-Lite interface allows you to dynamically control parameters within the core. Core configuration can be accomplished using an AXI4-Lite master state machine, or an embedded Arm® , or a soft system processor such as a MicroBlaze™ processor.

The Sensor Demosaic core can be controlled through the AXI4-Lite interface by using functions provided by the driver in the Vitis software platform. Another method is performing read and write transactions to the Sensor Demosaic register space, but this method should only be used when the first method is not available.
