    摘要： A system for selecting a subset of issued flash storage commands to improve processing time for command execution. A plurality of ports stores a first plurality of command identifiers and are associated with the plurality of ports. Each of the first plurality of arbiters selects an oldest command identifier among command identifiers within each corresponding port resulting in a second plurality of command identifiers. A second arbiter makes a plurality of selections from the second plurality of command identifiers based on command identifier age and the priority of the port. A session identifier queue stores commands associated with the plurality of selections among other commands forming a third plurality of commands. A microcontroller selects an executable command from the third plurality of commands for execution based on an execution optimization heuristic. After execution of the command, the command identifier in the port is cleared.

    摘要： A memory controller, in one embodiment, includes a command translation data structure, a front end and a back end. The command translation data structure maps command operations to primitives, wherein the primitives are decomposed from command operations determined for one or more memory devices. The front end receives command operations from a processing unit and translates each command operation to a set of one or more corresponding primitives using the command translation data structure. The back end outputs the set of one or more corresponding primitives for each received command operation to a given memory device.

    摘要： A system for improving direct memory access (DMA) offload. The system includes a processor, a data DMA engine and memory components. The processor selects an executable command comprising subcommands. The DDMA engine executes DMA operations related to a subcommand to perform memory transfer operations. The memory components store the plurality of subcommands and status data resulting from DMA operations. Each of the memory components has a corresponding token associated therewith. Possession of a token allocates its associated memory component to the processor or the DDMA engine possessing the token, making it inaccessible to the other. A first memory component and a second memory component of the plurality of memory components are used by the processor and the DDMA engine respectively and simultaneously. Tokens, e.g., the first and/or the second, are exchanged between the DDMA engine and the processor when the DDMA engine and/or the microcontroller complete accessing associated memory components.

    摘要： The wear-leveling techniques include discovering a persistent state of one or more memory devices, or building and caching persistent state parameters for each logical unit of a given memory device if a persistent state is not discovered for a given memory device. The techniques may also include processing memory access commands utilizing the cached persistent state parameters. When processing memory access commands, the logical block address and length parameter of a logical address of a command may be translated to a plurality of physical addresses for accessing one or more memory devices, each physical address includes a device address, a logical unit address, a block address, and a page address, wherein the block address includes one or more interleaved address bits.
