Multiple bus system and data transmission method using the same

摘要

PURPOSE: A multi-bus system and a data transmitting method using the same for transmitting data through a shared memory without passing through a bridge are provided to improve the effectiveness of data transmission by reducing data transfer time in multiple bus system including a plurality of masters and slave. CONSTITUTION: A first memory selector(180) controls connection to a first shared memory(160) of a plurality of masters. A second memory selector controls connection to the second shared memory of masters. A first common bus(110) transmits and receives signal between the first memory selector and the master. A second common bus transmits and receives signal between the second memory selection and masters. Signal of the first master requesting the first memory selector connects the master other shared memory each other connected with the common bus.
