Protocol conversion and arbitration circuit, System having the same, and method for converting and arbitrating signals

Arbitration protocol conversion circuit and the signal conversion system and the arbitration method comprising same are disclosed. A protocol conversion arbitration circuit protocol conversion circuit for receiving a signal according to a protocol that is used master, and converts the received signal into a signal in accordance with the protocol used by the system bus slave in use; And a converting circuit for converting into a signal in accordance with the protocol for receiving the output signal from the protocol conversion circuit, wherein the slave using the received signals. Through a multi-port memory controller and the at least one protocol conversion arbitration circuit system, a plurality of modules directly to the multi-port memory controller without each passing through a system bus comprising a according to the invention can send and receive the external memory and data , there is an effect that the data processing time is significantly reduced.
