Description
〔A-1〕システム構成例
図1は、実施形態の一例における演算処理装置1のハードウェア構成例を模式的に示すブロック図である。
図1に示した演算処理装置1における演算処理を、図5に示すフローチャート(ステップS1~S8)に従って説明する。
上述した実施形態の一例における演算処理装置1によれば、例えば、以下の作用効果を奏することができる。
上述した実施形態の一例では、固定小数点レジスタ104に命令デコーダ114からの書き込みのための専用のポートを備えることとした。一方、本変形例では命令デコーダ114からの書き込みのための専用のポートを固定小数点レジスタ104に増やさずに、固定小数点レジスタ104への書き込みを実現する。
開示の技術は上述した実施形態に限定されるものではなく、本実施形態の趣旨を逸脱しない範囲で種々変形して実施することができる。本実施形態の各構成及び各処理は、必要に応じて取捨選択することができ、あるいは適宜組み合わせてもよい。
