Abstract: The present disclosure provides computer-implemented methods, systems, and devices for controlling an external shared clock in a computing system with a plurality of system on a chips (SoCs). To do so, while a first SoC is in a low power mode, the second SoC receives a wake-up input that causes the second SoC to exit a low power mode. The second SoC asserts a clock request signal line to activate an external shared clock. The clock control system determines a state associated with the external shared clock, wherein the external shared clock is external to the first SoC. The clock control system, in accordance with a determination that the external shared clock is in an off state, transmits a signal to the external shared clock to cause the external shared clock to enter a startup state and begin producing a shared clock signal.

Abstract: Email has become commonplace as a means to communicate among parties non-synchronously by exchanging email messages. Some communications, however, may be more effective in real-time or in near real-time. For instance, service providers may offer a chat feature to accommodate real-time or near real-time help or service communications with customers. However, in this case, the user is likely required to enter credentials and/or context information to transition into a different communication type with the service provider. The present systems and methods provide a continuous conversation experience for the user whereby a message recipient of one message type (e.g., email, text, etc.) may continue a conversation in a different message type (e.g., a chat session, instant message, etc.) without manually providing message context for communicating via the second message type.
