ABSTRACT:
A method for optimizing a program by performing a data batch transfer between a first and second memories when data is read from the second memory into the first memory and when the data is written from the first memory into the second memory. The optimization processing includes analyzing the preference order relation of the accesses, in a loop procedure having accesses to array data in the second memory, classifying the array accesses in the loop into groups that need to be shared in the storage regions in which the data are temporarily stored in the first memory, finding the sum of sets of access elements for the accesses pertaining to each of the groups, determining a range of transferring the data, and generating, outside the loop, an instruction code for batchwisely making accesses to the array data on a transfer range pertaining to each of the groups.
