Abstract: A memory, such as a non-volatile ferroelectric memory, including both error correction coding (ECC) capability and redundant memory cells. During the system operating life of the memory, upon ECC decoding determining that a symbol read from the memory array at an address cannot be corrected, the failed memory cells are identified, and redundancy enabled to replace those failed cells if available. Redundant columns may be partitioned by row address, to allow the same column of redundant cells to replace bits in different columns for different portions of the memory. Dynamic redundancy is provided by the disclosed embodiments, extending the reliability of the memory during its system operating life.

Abstract: Systems, methods and articles of manufacture provide for determining the capabilities of a remote mobile devices (e.g., determining the processing capability and/or memory capacity). In one embodiment, capability is determined by displaying a series of images and measuring the time required to display those images. Different series of images, comprising different numbers of images, may be displayed and the corresponding times for each series compared. A particular version of software (or a configuration or parameter of software) to be output to or on the mobile device is then selected based on the determined capabilities. For example, graphics which do not require relatively low processing power and/or memory capacity may be selected for output of an electronic game if the mobile device is determined to have relatively low capabilities.

Abstract: A switched fabric hierarchy (e.g., a PCIe hierarchy) may utilize hardware, firmware, and/or software for filtering duplicative or otherwise undesirable correctable error messages from reaching a root complex. An operating system of the root complex may detect a persistent stream or storm of correctable errors from a particular endpoint and activate filtering of correctable errors from that endpoint. A filtering device may receive filtering commands and parameters from the operating system, implement the filtering, and monitor further correctable errors from the offending device. While an offending device is being filtered, correctable error messages from the offending device may be masked from the operating system, while correctable error messages from other devices in the switched fabric hierarchy may be transmitted.

Abstract: A massively parallel real-time computing system receives input data events across many compute nodes, each with a processing algorithm in its processing pipeline. An Event Manager is placed before the algorithm processing pipelines, receives metadata about each incoming event, and collects and organizes it in a database. A fast histogram compares the metadata about each event to that of all the other events, in a processing interval. For sufficiently matching metadata, the events are forwarded to the processing nodes as “regular” events for processing. If the metadata for a processing interval does not match sufficiently, the histogram decides which events are the “correct” events and which events are “incorrect.” The “correct” events are sent on for processing and the “incorrect” events are combined with the “correct” metadata and sent back to the processing nodes to supplement or modify their incoming data to match the other nodes' expectations.
