PROBLEM TO BE SOLVED: To provide a biological signal measurement device capable of decreasing an entire operation amount.SOLUTION: The biological signal measurement device includes: a biological signal measurement section for measuring a biological signal and an arithmetic processing section for arithmetically processing a measured biological signal. The arithmetic processing section has a first independently-controllable arithmetic processing part for executing an arithmetic processing required for calculation of the biological signal, and a second independently-controllable arithmetic processing part for executing a specific arithmetic processing. When the first arithmetic processing part meets a predetermined condition, it can make the second arithmetic processing part execute the specific arithmetic processing.COPYRIGHT: (C)2013,JPO&INPIT【課題】全体の演算量を減らすことができる。【解決手段】本発明の生体信号測定装置は、生体信号を測定する生体信号測定部と、測定された生体信号を演算処理する演算処理部と、を備え、前記演算処理部は、記生体信号の算出に必要な演算処理を行う独立して制御可能な第1演算処理部と、特定の演算処理を行う独立して制御可能な第2演算処理部と、を有し、前記第1演算処理部が所定条件を具備した場合に、前記第2演算処理部に特定の演算処理を実行させることを特徴とする。【選択図】図1
