PROBLEM TO BE SOLVED: To improve the processing capacity of a multiprocessor system. SOLUTION: This system comprises a slave processor 2 of SPI communication, a master processor 2 of SPI communication, an SPI cable 5 for connecting both the processors, and an SCI cable 4 for connecting both the processors. The slave processor 2 has a command communication part 220 for transmitting a communication request command for requesting at least one of transmission and receiving of data to the master processor 3 through the SCI cable 4, and the master processor 3 has a data communication part 310 for starting communication with the slave processor according to the communication request command from the slave processor 3 and transmitting and receiving data through the SPI cable 5.
