System for axi compatible network on chip and interleaving method thereof

An NoC(Networks on Chip) system applied with an AXI(Advanced Extensible Interface) and an interleaving method thereof are provided to select data to be transmitted, so that the data can be matched with the interleaving permissive capacity of an IP(Internet Protocol), thus the data can be smoothly transmitted, consequently performance of the system is improved. On either an NI(Network Interface)(120) or an NoC router(110), the following components are comprised. Data provided from each AXI IP are classified according to the AXI IPs and stored in plural buffers(143). An interleaving manager(147) selects one of the buffers(143) from which the data are to be outputted, according to the interleaving acceptance capacity which is the amount of interleaving data accepted in a the destination AXI IPs.
