Appeal No. 96-1765
Application No. 08/078,630
The invention is directed to the accessing of a multi-
dimensional array during loop processing, converting that
array to one that is more easily accessed during loop
processing and extracting the required data from the converted
array.
Representative independent claim 1 is reproduced as
follows:
1. A loop conversion method in an information
processing system having a processor and a memory, comprising:
a step performed by said processor, of generating an
instruction for accessing data formed of a plurality of source
array elements which are arrayed in a plurality of dimensions;
a step performed by said processor of recognizing an
accessing process of loop nest within codes containing said
instruction;
a step performed by said processor, of transposing and
copying the source array elements between at least two
positions on different dimensions in said plurality of
dimensions, to a one dimensional destination array including
at least a continuous array in said memory; and
a step performed by said processor, of converting an
access of said instruction to said source array elements to an
access to said destination array.
