Title (EN) TIME SHARING DEVICE FOR THE ACCESS TO A MAIN MEMORY CONNECTED TO A SINGLE BUS BETWEEN A CENTRAL COMPUTER AND A PLURALITY OF PERIPHERAL COMPUTERS
(FR) DISPOSITIF DE PARTAGE TEMPOREL DE L"ACCES A UNE MEMOIRE PRINCIPALE CONNECTEE A UN BUS UNIQUE ENTRE UN CALCULATEUR CENTRAL ET UNE PLURALITE DE CALCULATEURS PERIPHERIQUES
Abstract: front page image
(EN)Such a device is necessary in an installation comprising fast working peripheral computers allowing to unload a central computer and having only one main memory. The device (5) comprises a searching circuit (6) allowing to detect which peripheral computer (41, 42, 43)... has asked to be connected to the single bus (3) to have access to the main memory (2) and a decision circuit (7) authorizing the peripheral computer to be connected to the bus (3) according to the utilization state of the bus (3) and giving the order to all other computers to disconnect from the bus when the access to the memory (2) is possible. Application: time sharing data processing and, particularly, telephony.
(FR)Un tel dispositif est necessaire dans une installation incluant des calculateurs peripheriques rapides permettant de decharger un calculateur central et ne comportant qu"une memoire principale. Selon l"invention, le dispositif (5) comporte un circuit de scrutation (6) permettant de deceler le calculateur peripherique (41, 42, 43...) qui a demande a etre connecte au bus unique (3) pour avoir acces a la memoire principale (2) et un circuit de decision (7) accordant l"autorisation au calculateur peripherique de se connecter au bus (3) en fonction de l"etat d"utilisation du bus (3) et donnant l"ordre a tous les autres calculateurs de se deconnecter du bus lorsque l"acces a la memoire (2) est possible. Application: informatique temps reel et, en particulier, telephonie.
