Title (EN) METHOD AND APPARATUS FOR DATA BUFFER MANAGEMENT
(FR) PROCEDE ET APPAREIL PERMETTANT LA GESTION DE TAMPONS DE DONNEES
Abstract:
(EN) A data buffer management system (10) supervises the transmission of blocks of data between a first device (21), a data buffer (24), and a second device (26). In a write mode, blocks are transmitted to the second device (26) in an originally-intended sequence. If the second device (26) determines that a bad block was written thereto, the management system (10) rewrites the block in an alternate sequence. In a read mode, the management system (10) ignores bad blocks and duplicate blocks acquired from the second device (26) to transmit blocks of data to the first device (21) in the proper sequence.
(FR) Système de gestion (10) de tampons de données supervisant la transmission de blocs de données entre un premier dispositif (21), un tampon de données (24), et un second dispositif (26). Dans un mode d'écriture, des blocs sont transmis au second dispositif (26) dans une séquence de conception originale. Si le second dispositif (26) détermine qu'un bloc défectueux a été inscrit dans celui-ci, le système de gestion réécrit le bloc dans une séquence de remplacement. Dans un mode de lecture, le système de gestion (10) ignore les blocs défectueux et duplique les blocs obtenus à partir du second dispositif (26) afin de transmettre des blocs de données au premier dispositif (21) dans la bonne séquence.
