A digital microprocessor device (2) has: a central processing unit; a memory (8); and an output signal module (4). The output signal module comprises: a counter (6) arranged to count to a predetermined count value; and at least one comparator (10a, 10b, 10c) arranged to change an output signal (14a, 14b, 14c) from a first output state to a second output state when the counter reaches a predetermined comparator value. The output signal module is arranged to load automatically from the memory at least one parameter selected from the group comprising: the predetermined count value, the predetermined comparator value and the first output state or the second output state, without receipt of an instruction from the central processing unit.

A method, computer program product, and computing system for maintaining a first cursor pointer for a memory system, wherein the first cursor pointer concerns a first search criteria and identifies an initial first cursor starting location; receiving a first search request for the memory system that satisfies the first search criteria; executing the first search request within an initial first search window starting at the initial first cursor starting location; and updating the first cursor pointer to identify an updated first cursor starting location based, at least in part, upon the initial first search window.

Noise injection procedures implemented on the die of a non-volatile memory (NVM) array are disclosed. In one example, noise is injected into data by adjusting read voltages to induce bit flips while using feedback to achieve a target amount of information degradation. In another example, random data is iteratively combined with itself to achieve a target percentage of random 1s or 0s, then the random data is combined with data read from the NVM array. In other examples, pixels are randomly zeroed out to emulate dead charge coupled device (CCD) pixels. In still other examples, the timing, voltage, and/or current values used within circuits while transferring data to/from latches or bitlines are adjusted outside their specified margins to induce bit flips to inject noise into the data. The noise-injected data may be used, for example, for dataset augmentation or for the testing of deep neural networks (DNNs).

A method and a system for delivering a message in a storage system. In one embodiment of the present invention, there is provided a method for delivering a message in a storage system comprising a first controller, a second controller, a first communication area and a second communication area. The method comprises: in response to receiving a message that is to be delivered from the first controller to the second controller, writing the message to the first communication area that is readable and writable to the first controller and readable to the second controller; and writing an address identifier to the second communication area, the address identifier being used for indicating an address at which the second controller reads the message from the first communication area, the second communication area being readable to the first controller and readable and writable to the second controller.

Memory devices for facilitating pattern matching and having an array of memory cells, a plurality of key registers to store a representation of a key word, and a plurality of multiplexers, each multiplexer of the plurality of multiplexers to select a representation of a bit from a key register of the plurality of key registers to compare to data stored in the array of memory cells.

A method can include receiving data associated with a drilling operation in a geologic environment; determining a state based at least in part on the data; representing the state using a symbolic representation scheme that includes letters; storing the represented state in a database; and, for a combination of letters that represents a combination of states, performing a search engine based search of the database to generate a search result.

Apparatus and method for performing wear leveling are disclosed. An ordered list of references to each of a set of memory blocks is stored. A set of memory blocks in the ordered list is sequentially allocating. The allocated set of memory blocks in the ordered list are erased in the sequence in which they were allocated.

A data storage service stores a dataset on a set of storage nodes in accordance with a first encoding. A set of shards constituting quorum, and one or more additional shards, are stored on the storage nodes. The data storage system determines to store the dataset according to a second encoding, in which the second encoding has a greater number of shards. The data storage system reconfigures the storage of the dataset in accordance with the second encoding, such that the reconfigured storage forms additional shards for the second encoding by combining portions of shards of the first encoding.
