PROBLEM TO BE SOLVED: To provide a multiprocessor system capable of immediately using the execution results of other processors and performing parallel processing without a host processor. SOLUTION: The multiprocessor system includes a plurality of execution units PC0-PC3, a crossbar switch 120 for switching the execution part to be an input destination, crossbar switch registers XR0-XR3 connected to the crossbar switch and capable of being accessed by the plurality of computation execution parts, and a crossbar switch control instruction generation part for controlling the crossbar switch such that the value of the crossbar switch register to be an access object is inputted to the plurality of execution units on the basis of an instruction code. The crossbar switch 120 performs control such that the value of the crossbar switch register to be the access object is inputted to the plurality of execution units on the basis of a crossbar switch control instruction.
