NETWORK ON CHIP AND DATA TRANSMISSION METHOD FOR INTER COMMUNICATION OF SYSTEM ON CHIP, AND RECORDING MEDIUM STORING PROGRAM FOR EXECUTING METHOD OF THE SAME IN COMPUTER

摘要

PURPOSE: A network-on-chip (NOC) for the internal communications of a system-on-chip (SOC), a data transmission method thereof, and a recording medium containing a program to implement the method in a computer are provided to offer a bidirectional channel-based NOC router for the router connection of the NOC, thereby enabling the entire connection channel to be used for data transmission regardless of directivity. CONSTITUTION: Multiple routers (110,112,114,116) determine a communications path by transmitting a control packet and data among multiple components. Multiple unidirectional control channels (120) make connections between the multiple routers and between the multiple routers and the multiple components for the transmission of the control packet. Multiple bidirectional data channels (130) make connections between the multiple routers and between the multiple routers and the multiple components for the transmission of the data.
