  • Patent number: 7836233
    Abstract: A serial communication interface (SCI) cable 4 is provided between the slave processor 2 and the master processor 3. Both processors are connected with a communication interface for peripheral units (SPI: Serial Peripheral Interface) which enables fast transmission. The slave processor 2 transmits a transmission request command which requests at least one of data transmission and reception from the command communication section 220 to the master processor 3 through the SCI cable 4. The master processor 3 transfers data to and from the slave processor 2 in communication with the slave processor 2 by means of the data communication section 310 through the fast SPI cable 5 in response to a transmission request command sent from the slave processor 2 With this, the processing ability of a multi-processor system can be increased.
