Patent ID: 7861018

Claim:
A system for transmitting data in a network-on-chip (NoC) comprising: a NoC transmitter module; a NoC receiver module; a channel between said NoC transmitter module and said NoC receiver module for providing a first control signal from said NoC transmitter module to said NoC receiver module, and a second control signal from said NoC receiver module to said NoC transmitter module for initiating data transmission; and said NoC receiver module comprising a multi-stage buffer, and a controller cooperating therewith for synchronizing the first and second control signals, said multi-stage buffer comprising a first latch circuit for latching and delivering the first control signal in synchronization with a transmitter clock signal and being controlled by a first control driving signal based on the transmitter clock signal, and a second latch circuit for latching data provided by said first latch circuit, and delivering the data in synchronization with a receiver clock signal.
