ARITHMETIC UNIT, PROCESSOR, COMPILER AND COMPILING METHOD

摘要

An arithmetic unit which includes: a data supply section which supplies floating-point type object data to which a sign is to be added and condition data which includes a condition under which the sign is added; a sign data generating section which extracts the condition included in the condition data and generates sign data for adding the sign to the object data on the basis of the extracted condition; and an integer arithmetic operation section which performs an integer arithmetic operation while treating the object data as integer type data so as to add the sign to the object data on the basis of the sign data and the object data.
