    摘要： 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.

    摘要： A method and system for queueing data within a data storage device including a set of storage blocks each having an address, a pointer field, and a data field. This set of storage blocks comprises a linked list of associated storage blocks and also a free pool of available storage blocks. The storage device further includes a tail register for tracking an empty tail block from which a data object is enqueued into the linked list. A request to enqueue a data object into the linked list is received within the data storage system. In response to the data enqueue request, an available storage block from the free pool is selected and associated with the tail register. A single write operation is then required to write the data object into the data field of a current tail block and to write the address of the selected storage block into the pointer field of the current tail block, such that the selected storage block becomes a new tail block to which the tail register points.

    摘要： A method and apparatus implement memory accesses to a memory using an open page mode with data prefetching. A central processor unit issues memory commands. A memory controller receiving the memory commands, identifies a data prefetching command. The memory controller checks whether a next sequential line for the identified prefetch command is within the page currently being accessed, and responsive to identifying the next sequential line being within the current page, the current command is processed and the current page left open.

    摘要： A system, method and computer program features of the present invention, relate to verification or simulation of a design using a behavioral model structure for use in a Client/Server configuration. A physical part presents the external interface, and a functional procedural part which is comprised of at least one VHDL process. A testcase is a set of procedure calls written in VHDL. The present invention describes the architecture and implementation of a client/server behavioral model and procedural approach for testcase development which results in significant gain in productivity, quality of logic verification, and portability.
