(EN) ACCUMULATOR CIRCUIT AND METHOD OF USE THEREOF
(FR) CIRCUIT ACCUMULATEUR ET SON MODE D'UTILISATION
Abstract
(EN)
An accumulator is provided which includes a plurality of summing circuits (24a-24h), a plurality of switches (32b-32h), and a control unit (20) for controlling the transmission of data generated by the summing circuits. Each summing circuit generates intermediate sums and includes a port for transmitting the intermediate sums. The switches are connected between the ports of the summing circuits. The control unit is programmable to operate the switches and enable the ports at various times, thus allowing the accumulator to be configured to perform any of a variety of summing operations.
(FR)
L'invention porte sur un accumulateur qui comprend une pluralité de circuits additionneurs (24a-24h), une pluralité de commutateurs (32b-32h), et une unité de commande centrale (20) destiné à gérer la transmission de données générées par les circuits additionneurs. Chaque circuit additionneur génère des sommes intermédiaires et il comprend un port destiné à transmettre les sommes intermédiaires. Les commutateurs sont connectés entre les ports des circuits additionneurs. L'unité de commande est programmable pour faire fonctionner les commutateurs et valider les ports à différents temps, permettant ainsi à l'accumulateur d'être configuré pour effectuer une opération donnée parmi plusieurs opérations d'addition possibles.
