Disclosed are a method and a system for implementing synchronous parallel transmission over multiple channels. The method comprises: a sending end and a receiving end accessing an NoC through a sending port and a receiving port on the NoC, the sending port and the receiving port having a capability of simultaneously and parallely transmitting data; the sending end sending data to the sending port of the NoC, and the sending port encoding the received data into a bipolar data symbol and modulating the bipolar data symbol by using a Walsh code; then the NoC synchronously adding and combining modulated symbols of all sending ports, and sending a signal after the combination to each receiving port through an NoC bus synchronously and parallely; and the receiving port demodulating the received combined data according to the Walsh code thereof to obtain the bipolar data symbol, and then decoding the bipolar data symbol and sending the decoded bipolar data symbol to the receiving end. The present invention implements the synchronous parallel transmission over multiple channels, and one or more channels can be dynamically allocated to each NoC port so as to adapt to different communication bandwidth requirements. |
