摘要： An auto-commit memory is capable of implementing a pre-configured, triggered commit action in response to a failure condition, such as a loss of power, invalid shutdown, fault, or the like. A computing device may access the auto-commit memory using memory access semantics (using a memory mapping mechanism or the like), bypassing system calls typically required in virtual memory operations. Since the auto-commit memory is pre-configured to commit data stored thereon in the event of a failure, users of the auto-commit memory may view these memory semantic operations as being instantly committed. Operations to commit the data are taken out of the write-commit path.

摘要： A storage controller may be configured to assess the reliability of a solid-state storage medium. The storage controller may be further configured to project, forecast, and/or estimate storage reliability at a future time. The projection may be based on a currently reliability metric of the storage and a reliability model. The portions or sections of the solid-state storage media may be retired in response the projected reliability metric failing to satisfy a reliability threshold. The reliability threshold may be based on data correction and/or reconstruction characteristics. The projected reliability metrics of a plurality of erase blocks of a storage division may be combined, and one or more of the erase blocks may be retired in response to determining that the combined reliability metric projection fails to satisfy the reliability threshold.

摘要： Camera system and methods to capture panoramic imagery from a camera mounted on a moving platform, using low-cost digital image sensors. The panoramic imagery appears seamless and natural to the eye. The panoramic imaging system and methods are specifically designed to accommodate the long acquisition times of low-cost digital image sensors, despite the motion of the camera during image capture. Pairs of cameras are arranged about an axis and a pairwise firing sequence enables capturing a series of adjacent images without gap or overlap. Additionally, when combined with suitable supplemental sensors, the image data provide location information about objects in the image for use in elementary photogrammetry.

摘要： A storage controller identifies a storage division comprising unreadable data. In response, the storage controller relocates readable data (if any) from the identified storage division. The storage controller may be further configured to associate the unreadable data with a logical address, and to record persistent metadata to indicate that the logical address is mapped to unreadable, corrupt data. The storage controller may clear the corruption indicator from the logical address. The logical address may be cleared in response to determining that the unreadable data is invalid and/or available from another source.

摘要： Data of a vector storage request pertaining to one or more disjoint, non-adjacent, and/or non-contiguous logical identifier ranges are stored contiguously within a log on a non-volatile storage medium. A request consolidation module modifies one or more sub-requests of the vector storage request in response to other, cached storage requests. Data of an atomic vector storage request may comprise persistent indicators, such as persistent metadata flags, to identify data pertaining to incomplete atomic storage requests. A restart recovery module identifies and excludes data of incomplete atomic operations.

摘要： A method and apparatus for storing data packets in two different logical erase blocks pursuant to an atomic storage request is disclosed. Each data packet stored in response to the atomic storage request comprises persistent metadata indicating that the data packet pertains to an atomic storage request. In addition, a method and apparatus for restart recovery is disclosed. A data packet preceding an append point is identified as satisfying a failed atomic write criteria, indicating that the data packet pertains to a failed atomic storage request. One or more data packets associated with the failed atomic storage request are identified and excluded from an index of a non-volatile storage media.

摘要： Embodiments are disclosed relating to garbage collecting storage blocks in a storage device. In one embodiment, data is selected for relocation from a storage block in a storage device during reclaiming of the storage block. The data may be selected based on metadata that identifies whether data is valid at a time when the reclaiming is initiated. In some embodiments, prior to relocating data from the storage block, the metadata is captured from a data structure that identifies whether data on the storage device is valid. In one embodiment, a determination of whether the selected data has become invalid due to other data that is stored during the reclaiming is made. In some embodiments, in response to determining that the selected data has become invalid, the selected data is specified as invalid in the data structure.

摘要： A computer is programmed to identify types of variables, in a computer program which includes a number of variables that are used without any explicit indication of their type, by repeatedly performing at least propagation of types from variables' definitions to variables' uses and removal of unreachable code. Repetition of type propagation from definitions to uses and removal of unreachable code is one aspect of the invention. The repetition can be terminated differently in different embodiments. In many embodiments, the repetition is performed until no unreachable code is found.

摘要： A sensitive high speed clocked comparator for use with low level differential logic circuits which utilizes an amplifier, a Gilbert Gain Cell, and load devices to amplify the difference between analog voltages being compared, and a high speed latch to increase the output voltage level of the Gain Cell up to the level of logic signals used in low level differential logic circuits. The circuit has two modes, a "follow" mode wherein the amplifier and Gilbert Gain Cell cause an unbalance in the currents through two load devices responsive to any difference in input voltage, and a "latch" mode wherein a latch causes the current unbalance to increase and to latch. The modes are sequentially selected by clocking.
