    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.

    摘要: A virtual address translation table and an on-chip address cache are usable for translating virtual addresses to physical addresses. Address translation information is provided using a cluster that is associated with some range of virtual addresses and that can be used to translate any virtual address in its range to a physical address, where the sizes of the ranges mapped by different clusters may be different. Clusters are stored in an address translation table that is indexed by virtual address so that, starting from any valid virtual address, the appropriate cluster for translating that address can be retrieved from the translation table. Recently retrieved clusters are stored in an on-chip cache, and a cached cluster can be used to translate any virtual address in its range without accessing the address translation table again.

    摘要: A processor system suitable to provide an interface between networks includes a software programmable processor and a channel processor that receives data from a network and transforms data at commands from the software programmable processor. The channel can execute only a few simple commands, but these commands are sufficient for a wide range of systems. The commands include (1) a command to transmit received data, perhaps skipping some data; and (2) a command to transmit data specified by the command itself rather than the received data. The channel is fast, simple and inexpensive.

    摘要: In a multi-tasking pipelined processor, consecutive instructions are executed by different tasks, eliminating the need to purge an instruction execution pipeline of subsequent instructions when a previous instruction cannot be completed. The tasks do not share registers which store task-specific values, thus eliminating the need to save or load registers when a new task is scheduled for execution. If an instruction accesses an unavailable resource, the instruction becomes suspended, allowing other tasks' instructions to be executed instead until the resource becomes available. Task scheduling is performed by hardware; no operating system is needed. Simple techniques are provided to synchronize shared resource access between different tasks.

    摘要: A system, apparatus, and method are disclosed for storing predictions as well as examining and using one or more caches for anticipating accesses to a memory. In one embodiment, an exemplary apparatus is a prefetcher for managing predictive accesses with a memory. The prefetcher can include a speculator to generate a range of predictions, and multiple caches. For example, the prefetcher can include a first cache and a second cache to store predictions. An entry of the first cache is addressable by a first representation of an address from the range of predictions, whereas an entry of the second cache is addressable by a second representation of the address. The first and the second representations are compared in parallel against the stored predictions of either the first cache and the second cache, or both.
