METHOD AND APPARATUS FOR DATA BUFFER MANAGEMENT

摘要

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.
