Abstract
(EN)
This computation device is provided with a plurality of input lines and one or more multiply-accumulate computation devices. Each of the plurality of input lines receives an input of an electrical signal corresponding to an input value within a prescribed input period. On the basis of the electrical signals which are inputted into each of the plurality of input lines, a plurality of multiplication units of the multiply-accumulate computation device generates charges which correspond to multiplication values obtained by multiplying the input values by charge values. An accumulation unit of the multiply-accumulate computation device accumulates the charges which correspond to the multiplication values which are generated by each of the plurality of multiplication units. After the input period, a charging unit of the multiply-accumulate computation device charges the accumulation unit in which the charges which correspond to the multiplication values are accumulated. After the charging by the charging unit commences, an output unit of the multiply-accumulate computation device outputs a multiply-accumulate signal which represents the sum of the multiplication values by executing a threshold check against the voltage retained by the accumulation unit using a prescribed threshold. The charging by the charging unit is executed in a common charging manner, and a common threshold is set as the prescribed threshold.

L'invention concerne un dispositif de calcul pourvu d'une pluralité de lignes d'entrée et d'un ou de plusieurs dispositifs de calcul de multiplication-accumulation. Chaque ligne parmi la pluralité de lignes d'entrée reçoit une entrée d'un signal électrique correspondant à une valeur d'entrée dans une période d'entrée prescrite. Sur la base des signaux électriques entrés dans chaque ligne parmi la pluralité de lignes d'entrée, une pluralité d'unités de multiplication du dispositif de calcul de multiplication-accumulation génère des charges qui correspondent à des valeurs de multiplication obtenues par multiplication des valeurs entrées par les valeurs de charge. Une unité d'accumulation du dispositif de calcul de multiplication-accumulation accumule les charges qui correspondent aux valeurs de multiplication qui sont générées par chaque unité parmi la pluralité d'unités de multiplication. Après la période d'entrée, une unité de charge du dispositif de calcul de multiplication-accumulation charge l'unité d'accumulation dans laquelle les charges qui correspondent aux valeurs de multiplication sont accumulées. Après que la charge par l'unité de charge commence, une unité de sortie du dispositif de calcul de multiplication-accumulation délivre un signal de multiplication-accumulation qui représente la somme des valeurs de multiplication par exécution d'une vérification de seuil par rapport à la tension retenue par l'unité d'accumulation à l'aide d'un seuil prescrit. La charge par l'unité de charge est exécutée d'une manière de charge commune et un seuil commun est défini comme étant le seuil prescrit.

演算装置は複数の入力線と1以上の積和演算装置とを具備する。複数の入力線は、所定の入力期間内に入力値に応じた電気信号がそれぞれ入力される。積和演算装置の複数の乗算部は、複数の入力線の各々に入力される電気信号に基づいて、入力値に荷重値を乗算した乗算値に対応する電荷を生成する。積和演算装置の蓄積部は、複数の乗算部の各々により生成された乗算値に対応する電荷を蓄積する。積和演算装置の充電部は、入力期間後に、乗算値に対応する電荷が蓄積された蓄積部を充電する。積和演算装置の出力部は、充電部による充電の開始後、蓄積部により保持される電圧に対して所定の閾値により閾値判定を実行することで、乗算値の和を表す積和信号を出力する。充電部による充電が共通の充電態様で実行され、所定の閾値として共通の閾値が設定される。
