Abstract

PURPOSE:To increase an object efficiency and to increase the using efficiency of a memory by preparing an instruction necessary to the access considering a field length, an arithmetic size, etc., besides the code of a bit field. CONSTITUTION:The field length, code and arithmetic size of a bit field defined by a program language are outputted from an output means 10. The information concerning the bit fields to be accessed and respective access sizes from an access size data part 12 are given to a deciding means 14. The assembler instruction preparing identifying information determined by the information is outputted from the deciding means 14. The assembler instruction necessary to the above- mentioned access determined by the assembler instruction preparing identifying information is prepared by a preparing means 16. As the result, the object efficiency is lowered and the memory using efficiency can be lowered.
