  • Patent number: 10948969
    Abstract: A processing system includes multiple processors in which a first processor operates at a first clock frequency and first supply voltage at all times. At least one processor is dynamically switchable to operate at the first clock frequency and first supply voltage resulting in the first and second processors providing symmetrical multi-processing (SMP) or at a second clock frequency and a second supply voltage resulting in the first and second processors providing asymmetrical multi-processing (ASMP). An integrated controller (e.g., finite state-machine (FSM) controls not only voltage change, but also clock-switching. Various criteria can be used to determine when to switch the at least one switchable processor to improve power consumption and/or performance. Upon receipt of a switching command to switch between SMP and ASMP, a series or sequence of actions are performed to control a voltage supply and CPU/memory clock to the switchable processor and cache memory.

  • Patent number: 10271298
    Abstract: In certain embodiments, a method includes initiating, by a mobile device, an attempt to connect to a visiting network and receiving, by the mobile device in response to the attempt to connect to the visiting network, a rejection from the visiting network. The method includes initiating, by the mobile device in response to the rejection from the visiting network, a limited-services timer to initiate a limited-services state for the mobile device. The mobile device is subscribed to a service on a home network of the mobile device and is prevented in the limited-services state from attempting to access the service. The method further includes detecting, by the mobile device prior to expiration of the limited-services timer, availability of the home network and permitting, by the mobile device prior to expiration of the limited-service timer, the mobile device to attempt to connect to the home network for accessing the service.
