COMPILING METHOD AND COMPUTER READABLE RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To generate a program with the small number of executing instructions and with small size for a source program to perform a plurality of data access such as array reference without burdening a programmer. SOLUTION: The source program is scanned, a list of a group of data access by array reference points or an array reference formula is generated (S1) and a calculation formula of individual memory addresses is created next (S2). Data access by the memory address calculation formula in an address range to be efficiently treated by an instruction system as a given 16-bit fixed length instruction is grouped (S3), a base address formed by commonizing address calculation is selected to the grouped array reference (data access) and array as plural data access is made possible to be referred by the sum of the selected base address and offset (S4). No troublesome description of pointing code is required.
