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.
Claims5
A numerical controller having a function of prefetching blocks of a program, the numerical controller comprising:
- a prefetch sufficiency determination section configured to determine whether or not block prefetching from the program is sufficient based on whether or not at least one block subsequent to a predetermined reference block existing after a running block of the program has been prefetched, the at least one block being needed to execute the reference block;
- and
- a prefetch analysis section configured to perform block prefetching from the program if the prefetch sufficiency determination section determines that block prefetching from the program is not sufficient.
