Abstract
A serial communication interface (SCI) cableis provided between the slave processorand the master processor. Both processors are connected with a communication interface for peripheral units (SPI: Serial Peripheral Interface) which enables fast transmission. The slave processortransmits a transmission request command which requests at least one of data transmission and reception from the command communication sectionto the master processorthrough the SCI cable. The master processortransfers data to and from the slave processorin communication with the slave processorby means of the data communication sectionthrough the fast SPI cablein response to a transmission request command sent from the slave processor With this, the processing ability of a multi-processor system can be increased.
