ABSTRACT:
A packet data communication on-chip interconnect system is provided including a network interface efficiently controlling a transaction performed between at least one master intellectual property (IP) block and at least one slave IP block connected via a Network on a Chip (NoC). According to an aspect of the present invention, traffic functioning and throughput of the entire NoC may be improved by appropriately controlling an operation of performing a lock operation according to an Advance eXtensible Interface (AXI) protocol in the network interface of the packet data communication on-chip interconnect system.
