【Abstract】 ARM’s AMBA4.0 could satisfy the requirements to the computer system from the bus bandwidth and communication complexity on the structure. The design and production base on AMBA4.0 has become the first choice of industry. With the respect to the requirement of efficient convert communication among multiple AXI protocols, this paper proposes a method for AXI Interconnect with multi-protocols support on FPGA. Firstly the feature and communication mode of AMBA4.0 is analyzed, then this paper provides an architectural patterns according to the characteristics of different AXI protocols. Finally, the key design thoughts and prioritization scheme are also introduced. The application shows the design can implement convert communication between different AXI protocols and different bit wide data.更多还原
