ARITHMETIC UNIT, PROCESSOR, COMPILER AND COMPILING METHOD

摘要

PURPOSE: An operator, a processor, a compiler, and a compiling method are provided to convert a sign of floating point type data at high speed on the basis of condition data including a sign addition condition. CONSTITUTION: A data provider(140) supplies floating point type target data which a sign is added and condition data including a sign addition condition. A sign data generator(160) extracts a condition included in the condition data and generates sign data for adding a sign to the target data on the basis of the condition. An integral operating unit(150) regards the target data as integral type data in order to add the sign to the sign data on the basis of the sign data and the target data and performs integer operation.
