Abstract: A canary update method according to some embodiments is disclosed. The canary update method includes executing, by a processor configured to process tasks including the canary, computer program instructions to perform operations including extracting, by a processor, a first value from an array including N values, setting the canary to the first value, determining that the canary is updated based on a canary flag value of a first task, extracting, when determined that the canary is updated, a second value from the array, and updating the canary of the first task to the second value. The processor is configured to access a memory through a mapping circuit, and the mapping circuit includes mapping information between a physical memory region in the memory corresponding to the first task and a virtual memory region associated with the mapping circuit.

Abstract: A method for preventing a task-signal deadlock arising due to contention for a mutex in a real-time operating system (RTOS) includes detecting, by a processing unit, a signal notification sent to a task for execution of a signal handler; identifying, by the processing unit, a mutex to be acquired by the signal handler, when the signal notification is detected; determining whether the identified mutex has been acquired by the task; and utilizing, by the processing unit, an alternative stack for execution of the signal handler, in response to determining that the mutex has been acquired by the task, for preventing a task-signal deadlock during the execution.

Abstract: An apparatus is configured to collect information related to a first activity and analyze the collected information to determine decision data. The information is stored in a first list of the source processing core for scheduling execution of the activity by a destination processing core to avoid cache misses. The source processing core is configured to transmit information related to the decision data using an interrupt, to a second list associated with a scheduler of the destination processing core, if the destination processing core is currently executing a second activity having a lower priority than the first activity.

Abstract: Embodiments herein provide a method and system for managing session across multiple electronic devices in a network system. The method includes receiving by a target electronic device a first message from a source electronic device which includes a request to transfer context associated with at least one ongoing session on the source electronic device. Further, the method includes sending a response message to the source electronic device which includes a confirmation for the context transfer to. Further, the method includes receiving a Carry Your Own Context (CYOC) container associated with the at least one ongoing session from the source electronic device, wherein the CYOC container consists of cellular parameter information required for seamless session transfer from the source electronic device to the target electronic device. Furthermore, the method includes completing the at least one session transfer using the cellular parameter information received in the CYOC container.
