Abstract
The present invention realizes a functional safety of a multiprocessor system without tightly coupling processor elements. When causing a plurality of processor elements to execute the same data processing and realizing a functional safety of the processor element, there is adopted a bus interface unit that performs control of performing safety measure processing when the non-coincidence of access requests issued from the processor elements has been fixed, and of starting access processing responding the access request when these access requests coincide with one another.
