摘要：In a memory in a computer system, buffers are defined by a buffer managementsystem. A set Buffers command defines a number (NP) of pools of buffers, and for eachpool, a pool size (PS) of the number of buffers in the pool and the size (BS) of the buffersin that pool. The buffer management system is initialized to store the buffer sizes and tocumulate and store the pool sizes. To address a buffer, the buffer management systemdetermines the address of the start of the buffer from the desired pool and buffernumbers, using the stored information. Also, for updating a paged flash memory, a pagePn of the flash memory (4024) is copied as an image page into RAM memory (4022), andthe image page is updated and written back into a different page in the flash memory. Amain record table (22) is held in a separate non-volatile memory (EEPROM 4026),

identifying valid page pages in the flash memory, and is updated when a page in the flashmemory has been updated. The main record table includes a CRC error detection section(25), and is copied into a back-up record table (23) immediately after it has been updated.
