PROBLEM TO BE SOLVED: To provide an array type arithmetic unit capable of switching a clock path following switching of a transfer path of a serial transfer bus inside an array type arithmetic unit, reducing a risk of developing hold timing contravention, and reducing a hold buffer insertion.SOLUTION: A data transfer control part determines a transfer path for transferring up-to-date structure information on the basis of the location of a constitutional information holding part that becomes an object to be updated when the data transfer control part is given one or more up-to-date constitutional information, and determines the arrangement of the up-to-date structure information at the transfer time. A clock path control part determines an inverse path for the transfer path of the up-to-date constitutional information determined by the data transfer control part, the constitutional information holding part of the object to be updated on the inverse path stores and updates the up-to-date constitutional information transferred in synchronizing with a clock, and the other constitutional information holding part except for the constitutional information holding part of the object to be updated is set so as to by-pass the clock. The clock control part supplies the number of clocks corresponding to a length of information showing the up-to-date constitutional information to the constitutional information holding part as the start edge on the inverse path. |
