The AXI GPIO provides a general purpose input/output interface to the AXI (Advanced eXtensible Interface) interface. This 32-bit soft IP core is designed to interface with the AXI4-Lite interface.
Key Features and Benefits
Supports the AXI4-Lite interface specification
Supports configurable single or dual GPIO channel (s)
Supports configurable channel width for GPIO pins from 1 to 32 bits
Supports dynamic programming of each GPIO bit as input or output
Supports individual configuration of each channel
Supports independent reset values for each bit of all registers
