LED array having transparent substrate with conductive layer for enhanced current spread
In a flip-chip LED assembly having an array of LEDs formed on the same substrate, different LEDs of the array have different distances to the n-contacts of the assembly. This may cause current crowding as current has to spread from the n-contacts through the substrate to each the farthest LEDs of the LED array, requiring LEDs that are farther away to be driven with a higher voltage in order to receive a desired amount of current. To spread current more evenly through the LED assembly and reduce a voltage difference between the closest and farthest LEDs of the array, a current spreading layer having a conductive material (e.g., a conductive oxide) is formed on a surface of the substrate of the LED assembly. The current spreading layer may be a bulk layer or be patterned to increase light extraction from the LEDs of the array. |

Virtual archiving of database records
A database-management system (DBMS) archives a record of a database table by updating the record's unique “Archived” field. This indicates that the record should be considered to have been archived despite the fact that the record has not been physically moved to a distinct archival storage area. When a query requests access to the table, the DBMS determines whether the query requests access to only archived data, only active data, or both. If both, the DBMS searches the entire table. Otherwise, the DBMS scans each record's Archived field to consider only those records that satisfy the query's requirement for either archived or active data. If the DBMS incorporates Multi-Version Concurrency Control (MVCC) technology, the DBMS combines this procedure with MVCC's time-based version-selection mechanism. |

Signaling mechanism for bus inversion
Methods, systems, and devices that support signaling mechanisms for bus inversion are described. A control signal that supports transferring information from a first controller to a second controller via a bus may also be configured to indicate whether or not data that is communicated over the bus is inverted. The control signal may be a control signal that enables reception of control information at the second controller. The control signal may be controlled by the first controller when data is transmitted to the second controller and may be controlled by the second controller when data is transmitted to the first controller. |

Dynamic delay calibration of devices attached to bus systems utilizing time-multiplexed clock and data lines
Systems and methods for performing dynamic adaption and correction for internal delays in devices connected to a common time-multiplexed bus. The methods allow devices to operate reliably at a higher bus frequency by correcting for inherent and unknown delays within the components and in the system by measuring the actual delays using multiple readings with this bus. The inherent noise and jitter are utilized to increase the precision of the measurements thereby essentially using this uncertainty as a self-dithering for increased resolution in the measurements. During adaption, the delays may be adjusted in multiple step sizes for a faster adaption time. |

Apparatus and method for controlling allocation of information into a cache storage
An apparatus and method are provided for controlling allocation of information into a cache storage. The apparatus has processing circuitry for executing instructions, and for allowing speculative execution of one or more of those instructions. A cache storage is also provided having a plurality of entries to store information for reference by the processing circuitry, and cache control circuitry is used to control the cache storage, the cache control circuitry comprising a speculative allocation tracker having a plurality of tracking entries. The cache control circuitry is responsive to a speculative request associated with the speculative execution, requiring identified information to be allocated into a given entry of the cache storage, to allocate a tracking entry in the speculative allocation tracker for the speculative request before allowing the identified information to be allocated into the given entry of the cache storage. The allocated tracking entry is employed to maintain restore information sufficient to enable the given entry to be restored to an original state that existed prior to the identified information being allocated into the given entry. The cache control circuitry is further responsive to a mis-speculation condition being detected in respect of the speculative request, to employ the restore information maintained in the allocated tracking entry for that speculative request in order to restore the given entry in the cache storage to the original state. Such an approach can provide robust protection against speculation-based cache timing side-channel attacks whilst alleviating the performance and/or power consumption issues associated with known techniques. |

Multiple multithreaded processors with shared data cache
A multi-core processor configured to improve processing performance in certain computing contexts is provided. The multi-core processor includes multiple processing cores that implement barrel threading to execute multiple instruction threads in parallel while ensuring that the effects of an idle instruction or thread upon the performance of the processor is minimized. The multiple cores can also share a common data cache, thereby minimizing the need for expensive and complex mechanisms to mitigate inter-cache coherency issues. The barrel-threading can minimize the latency impacts associated with a shared data cache. In some examples, the multi-core processor can also include a serial processor configured to execute single threaded programming code that may not yield satisfactory performance in a processing environment that employs barrel threading. |

Managing and maintaining multiple debug contexts in a debug execution mode for real-time processors
A real-time debugger implementation maintains and manages multiple debug contexts allowing developers to interact with real-time applications without “breaking” the system in which the debug application is executing. The debugger allows multiple debug contexts to exist and allows break points in real-time and non-real-time code portions of one or more applications executing on a debug enabled core of a processor. A debug monitor function may be implemented as a hardware logic module on the same integrated circuit as the processor. Higher priority interrupt service requests may be serviced while otherwise maintaining a context for the debug session (e.g., stopped at a developer defined breakpoint). Accordingly, the application developer executing the debugger may not have to be concerned with processing occurring on the processor that may be unrelated to the current debug session. |
