  • Patent number: 11972153
    Abstract: This disclosure provides techniques for managing writes of data useful for storage systems that do not permit overwrite of a logical address. One implementation provides a nonvolatile memory storage drive, such as a flash memory drive, that provides support for zoned drive and/or Open Channel-compliant architectures. Circuitry on the storage drive tracks storage location release metadata for addressable memory space, optionally providing to a host system information upon which maintenance decisions or related scheduling can be based. The storage drive can also provide buffering support for accommodating receipt of out-of-order writes and unentanglement and performance of out of order writes, with buffering resources being configurable according to any one of a number of parameters. The disclosed storage drive facilitates reduced error rates and lower request traffic in a manner consistent with newer memory standards that mandate that writes to logical addresses be sequential.

  • Patent number: 11616585
    Abstract: An outdoor satellite receiving unit (ODU) receives several independent satellite signals, selects two signals with a switch matrix, downconverts the two signals to a bandstacked signal with a high and a low band signal, and outputs the bandstacked signal on the same cable to receiver units. Several satellite signals can be selected in groups of two or more and output to independent receiver units. Signal selecting is performed at the received radio frequency (RF) and bandstacking is performed with a single downconversion step to an intermediate frequency (IF). Channel stacking on the same cable of more than two channels from several satellites can be achieved by using frequency agile downconverters and bandpass filters prior to combining at the IF output. A slow transitioning switch minimizes signal disturbances when switching and maintains input impedance at a constant value.

  • Patent number: 11470017
    Abstract: Management of immersive reality devices via a reduced competition core network component is disclosed. The reduced competition core network component can preferentially be reserved for immersive reality device data and can therefore exclude some or all other types of data typically associated with conventional wireless network devices, e.g., phone, tablet/laptop computers, IoT devices, etc. This can result in immersive reality data communication that does not have to compete with more generic data types for network or computing resources. Additionally, the reduced competition core network component can be divided into at least one reduced competition user-plane network component and at least one reduced competition control-plane network component. Use of a reduced competition user-plane network component can avoid generating additional carrier network traffic. Further, a reduced competition user-plane network component can facilitate non-carrier entity authentication, security protocols, etc.

  • Patent number: 10691602
    Abstract: To reduce overhead for cache coherence for shared cache in multi-processor systems, adaptive granularity allows tracking shared data at a coarse granularity and unshared data at fine granularity. Processes for adaptive granularity select how large of an entry is required to track the coherence of a block based on its state. Shared blocks are tracked in coarse-grained region entries that include a sharer tracking bit vector and a bit vector that indicates which blocks are likely to be present in the system, but do not identify the owner of the block. Modified/unshared data is tracked in fine-grained entries that permit ownership tracking and exact location and invalidation of cache. Large caches where the majority of blocks are shared and not modified create less overhead by being tracked in the less costly coarse-grained region entries.

When the first codec is a verifiable codec, the method further includes separating the first partially processed recovered data segment into an initial integrity value and a processed data segment. The method further includes calculating a new integrity value from the processed data segment. When the new integrity value substantially matches the initial integrity value, the method further includes indicating that the set of encoded data slices is authentic.

  • Patent number: 10289587
    Abstract: A crossbar switch comprises two or more data inputs 10, two or more data outputs 100, a buffer 30 between the inputs and the outputs, an arbiter 52 associated with each output and configured to select data from one of the inputs when there is contention at the output, a bypass 32 associated with the buffer so that the buffer can be enabled or disabled, and a buffer controller 60 configured to enable or disable the buffer. The buffer controller further includes an accumulator 70 configured to assess whether a time-based average of the contention rate, or an average injection rate, at the output associated with the buffer, has reached a predetermined threshold. This prevents the buffer being enabled when the contention is only intermittent, which reduces power consumption without significant loss of performance.
