摘要： PROBLEM TO BE SOLVED: To reduce unnecessary transfer processing of a data register and decrease the number of steps of a processing program by providing a predicate register updating means which can perform notification to other computing elements. SOLUTION: A B parameter added to a 2nd instruction word cmp.gt of an instruction word array 512 given to a computing element 2 corresponds to a predicate notification field (B field) and determines whether the update of a predicate register 205 is notified to other computing elements 1. Once this 2nd instruction word 512 is executed, not only a value held in a predicate register area O(pO) of the computing element 2, but also a value held in a predicate register area O(pO) of a computing element 1 are updated. When the value of the B field is 'true' since the B parameter is specified, selectors 106 and 206 select write data outputted from computing elements whose B fields are 'true' and store them in the predicate registers 105 and 205.
