Title (EN) DATA PROCESSING SYSTEM
(FR) SYSTEME DE TRAITEMENT DE DONNEES
Abstract: front page image
(EN)A data processing system includes first and second data processors (20, 38) and first and second memories (26, 42), the first processor (20) being adapted to write data into the first memory (26) and the second processor being adapted to write data into the first and second memories (26, 42). The first processor (20) which is slower than the second processor (38), has priority of access to the first memory (26). When the second processor (38) is unable to write into the first memory (26) because of a conflict with the first processor (20), the data stored in the second memory (42) by the second processor (38) is transferred to the first memory (26) after completion of the access operation by the first processor (20). Also, data stored by the first processor (20) in the first memory (26) is transferred to the second memory (42) under the control of the second processor (38). Thus both processors (20, 38) will have access to the same data.
(FR)Un systeme de traitement de donnees comprend une premiere et une seconde unites de traitement de donnees (20, 38) et une premiere et une seconde memoires (26, 42), la premiere unite de travail (20) etant disposee pour ecrire des donnees dans la premiere et la seconde memoire (26, 42). La premiere unite de travail (20) etant plus lente que la seconde unite (38), a priorite d"acces a la premiere memoire (26). Lorsque la seconde unite de travail (38) est incapable d"ecrire dans la premiere memoire (26) a cause d"un conflit avec la premiere unite de travail (20), les donnees stockees dans la seconde memoire (42) par la seconde unite de travail (38) sont transferees a la premiere memoire (26) apres achevement de l"operation d"acces par la premiere unite de travail (20). Ainsi, les donnees stockees par la premiere unite de travail (20) dans la premiere memoire (26) sont transferees a la seconde memoire (42) sous le controle de la seconde unite de travail (38). Ainsi les deux unites de travail (20, 38) auront acces aux memes donnees.
