Abstract
SISTEMA DE ACCESO A MODULOS DE MEMORIA. LA FUENTE DE ACESO A LA MEMORIA ESTA FORMADA POR UNA UNIDAD CENTRAL DE TRATAMIENTO (1) Y UNA UNIDAD DE CONTROL DE CANAL (2). UNA UNIDAD DE CONTROL (3) DE ACCESO A LA MEMORIA SIRVE DE PUENTE. DESDE UNOS REGISTROS DE DIRECCIONES (11, 21) SE MANDAN SEÑALES A UNA UNIDAD (31) FORMADORA DE DIAGRAMAS O MAPAS Y A UNA MEMORIA INTERMEDIA (32) DE DIRECCIONES DE LA UNIDAD DE CONTROL (3). LAS SALIDAS (MA12...MA18) DE LA MEMORIA INTERMEDIA (32) SON LLEVADAS A UN REGISTRO (41-2) DE DIRECCIONES DE MEMORIA; LAS SALIDAS (MA00..MA11), QUE FORMAN EL CODIGO DE DIRECCIONES, SON LLEVADAS A UN REGISTRO (41-1). DE ESTA FORMA SE ESTABLECE EL ACCESO, AL TIEMPO QUE UN CIRCUITO DE CONTROL (33'') GENERA LAS SEÑALES DE INICIACION DE MEMORIA.
