What is AXI4?

AXI4 (Advanced eXtensible Interface 4) is a high-performance, high-bandwidth, cache-coherent, on-chip interconnect standard widely used in System-on-Chip (SoC) designs. It defines a protocol for communication between master (initiator) and slave (target) components within a system. AXI4 facilitates efficient data transfer, supporting burst transactions and separate address/data phases. It is commonly used to connect processor cores, memory controllers, peripherals, and other functional blocks within a SoC, enabling high-speed data movement and system-level integration.
