Abstract
A numerical controller determines whether or not block prefetching from a program is sufficient based on whether at least one block subsequent to a predetermined reference block, which exists after a running block of the program and is needed to execute the reference block, has been prefetched or not. If the determination result is that prefetching is not sufficient, block prefetching from the program is performed.
