20150301955 | EXTENDING PROTECTION DOMAINS TO CO-PROCESSORS - Systems and methods relate to safely and efficiently operating a multiprocessing system involving cooperation of a first processor and a second processor. For example, with regard to a first process of a first processor to be handed off to a second processor for execution, a first memory protection domain (PD) is created in a common memory, the first memory PD corresponding to the first process. The first memory PD is extended between the first processor and the second processor such that the second processor is enabled to execute the first process within the first memory PD. With regard to the first process, accesses to the common memory by the first and second processors are limited to the first memory PD, which ensures safety of the first and second processors from one another. | 10-22-2015 |
20150301884 | CACHE MEMORY ERROR DETECTION CIRCUITS FOR DETECTING BIT FLIPS IN VALID INDICATORS IN CACHE MEMORY FOLLOWING INVALIDATE OPERATIONS, AND RELATED METHODS AND PROCESSOR-BASED SYSTEMS - Aspects disclosed herein include cache memory error detection circuits for detecting bit flips in valid indicators (e.g., valid bits) in cache memory following invalidate operations. Related methods and processor-based systems are also disclosed. If a cache hit results from access to a cache entry following an invalidate operation, a bit flip(s) has occurred in a valid indicator of the cache entry. This is because the valid indicator should indicate an invalid state following the invalidate operation of the cache entry, as opposed to a valid state. Thus, a cache memory error detection circuit is configured to determine if an invalidate operation was performed on the cache entry. The cache memory error detection circuit can cause a cache miss or an error for the accessed cache entry to be generated as a result, even though the valid indicator for the cache entry indicates a valid state due to the bit flip(s). | 10-22-2015 |
20150301573 | LATENCY-BASED POWER MODE UNITS FOR CONTROLLING POWER MODES OF PROCESSOR CORES, AND RELATED METHODS AND SYSTEMS - Latency-based power mode units for controlling power modes of processor cores, and related methods and systems are disclosed. In one aspect, the power mode units are configured to reduce power provided to the processor core when the processor core has one or more threads in pending status and no threads in active status. An operand of an instruction being processed by a thread may be data in memory located outside processor core. If the processor core does not require as much power to operate while a thread waits for a request from outside the processor core, the power consumed by the processor core can be reduced during these waiting periods. Power can be conserved in the processor core even when threads are being processed if the only threads being processed are in pending status, and can reduce the overall power consumption in the processor core and its corresponding CPU. | 10-22-2015 |

20150296523 | Enhanced Mobile Standby Performance During Simultaneous Dual-Technology Communication By Avoiding Interference Scenarios - The various embodiments include methods and apparatuses for avoiding interference scenarios during concurrent communication of dual-technology wireless communication devices. Interference scenarios may be avoided by predicatively determining the potential for interference between the channels of multiple communications on the dual-technology wireless communication devices. For a pending communication, a predicative calculation may be made to determine whether the channel of the pending communication and the channel of an active communication may interfere with each other. If so, the communication with a lower priority may switch to the highest powered channel that does not interfere with the higher priority communication. Once the interference condition expires, and the lower priority communication persists, its channel may switch to a higher power channel that will not cause interference with any active or pending communications. Switching the channel for a communication may be prompted by electromagnetic interference from components of the dual-technology wireless communication devices. | 10-15-2015 |
