    • A bandwidth conserving queue manager for a FIFO buffer is provided, preferably on an ASIC chip and preferably including separate DRAM storage that maintains a FIFO queue which can extend beyond the data storage space of the FIFO buffer to provide additional data storage space as needed. FIFO buffers are used on the ASIC chip to store and retrieve multiple queue entries. As long as the total size of the queue does not exceed the storage available in the buffers, no additional data storage is needed. However, when some predetermined amount of the buffer storage space in the FIFO buffers is exceeded, data are written to and read from the additional data storage, and preferably in packets which are of optimum size for maintaining peak performance of the data storage device and which are written to the data storage device in such a way that they are queued in a first-in, first-out (FIFO) sequence of addresses. Preferably, the data are written to and are read from the DRAM in burst mode.
    • 提供了用于FIFO缓冲器的带宽节省队列管理器,优选地在ASIC芯片上并且优选地包括单独的DRAM存储器,该DRAM存储器维护可以延伸超出FIFO缓冲器的数据存储空间的FIFO队列以根据需要提供额外的数据存储空间。 在ASIC芯片上使用FIFO缓冲区来存储和检索多个队列条目。 只要队列的总大小不超过缓冲区中可用的存储空间,就不需要额外的数据存储。 然而,当FIFO缓冲器中的一些预定量的缓冲存储空间被超过时,数据被写入附加数据存储装置并从附加数据存储装置中读取,并且优选地以具有最佳尺寸的数据包来维持数据存储装置的峰值性能, 以这样的方式被写入数据存储设备,使得它们以先进先出(FIFO)地址序列排队。 优选地,数据被写入并以突发模式从DRAM读取。
