Abstract: Methods and apparatus for synchronization of time between independently operable processors. Time synchronization between independently operable processors is complicated by a variety of factors. For example, neither independently operable processor controls the other processor's task scheduling, power, or clocking. In one exemplary embodiment, a processor can initiates a time synchronization process by disabling power state machines and transacting timestamps for a commonly observed event. In one such embodiment, timestamps may be transferred via inter-processor communication (IPC) mechanisms (e.g., transfer descriptors (TDs), and completion descriptors (CDs)). Both processors may thereafter coordinate in time synchronization efforts (e.g., speeding up or slowing down their respective clocks, etc.).

Abstract: A computer comprising one or more processors and memory may implement an atomic compare and swap (CAS) operation on multiple data elements. Each data element has a corresponding descriptor which includes a new value and a reference to a controlling descriptor for the CAS operation. The controlling descriptor includes a status value which indicates whether the CAS operation is in progress or has completed. The operation first allocates memory locations of the data elements by writing addresses of respective descriptors to the memory locations using CAS instructions. The operation then writes successful status to the status value of the controlling descriptor to indicate that the respective memory locations are no longer allocated. The operation then returns an indicator of successful completion without atomically updating the memory locations with the new values. Extensions are further described to implement CAS operations in non-volatile random access memories.

Abstract: Methods and apparatus for time sensitive data transfer between logical domains. In one embodiment, an user equipment (UE) device has an application processor (AP) coupled to a baseband processor (BB) that operate independently of one another normally, but may cooperate in limited hybrid use scenarios. For example, the BB receives audio packets via a cellular network that are converted to pulse code modulated (PCM) digital audio to be played by the AP. Unfortunately, since the AP and the BB are independently clocked, they will experience some clock drift. As a result, the audio playback may have undesirable artifacts if the drift is not otherwise compensated for. To these ends, the AP and/or BB determine a relative clock drift and compensate for playback by e.g., adding, padding, or deleting audio samples and/or audio packets. Techniques for handover scenarios are also disclosed.

Abstract: Systems, methods, and articles of manufacture provide for fault-tolerant timers, such as in an online gaming environment. Fault-tolerant timers may, for example, be provided by implementing specific methods for expiring a timer, such as by utilizing broadcast notices and distributed locks.

Abstract: Exemplary aspects are directed toward resolving fault suppression in hardware, which at the same time does not incur a performance hit. For example, when multiple instructions are executing simultaneously, a mask can specify which elements need not be executed. If the mask is disabled, those elements do not need to be executed. A determination is then made as to whether a fault happens in one of the elements that have been disabled. If there is a fault in one of the elements that has been disabled, a state machine re-fetches the instructions in a special mode. More specifically, the state machine determines if the fault is on a disabled element, and if the fault is on a disabled element, then the state machine specifies that the fault should be ignored. If during the first execution there was no mask, if there is an error present during execution, then the element is re-run with the mask to see if the error is a “real” fault.
