Summary:PROBLEM TO BE SOLVED: To provide execution of rounding operations corresponding to instructions.SOLUTION: In one embodiment, the present invention includes a method including the steps of: receiving a rounding instruction and an immediate value in a processor; determining whether a rounding mode override indicator of the immediate value is active; and executing, if the rounding mode override indicator of the immediate value is active, a rounding operation on a source operand in a floating point unit of the processor in response to the rounding instruction and according to a rounding mode described in an immediate operand. Other embodiments are described and claimed.SELECTED DRAWING: Figure 1 【課題】命令に応じた丸め処理の実行を提供する。【解決手段】ある実施形態では、本発明は、プロセッサにおいて丸め命令および直接値を受領し、前記直接値の丸めモード・オーバーライド指標がアクティブであるかどうかを判定し、もしアクティブであれば、前記丸め命令に応答して、前記直接オペランドに記述されている丸めモードに従って前記プロセッサの浮動小数点ユニットにおいてソース・オペランドに対して丸め処理を実行することを含む方法を含む。他の実施形態も記載され、特許請求される。【選択図】図１
