Abstract: A multicore computing device includes a memory and a processor coupled to the memory. The processor includes plural cores and a multiple input multiple output (MIMO) block coupled to the cores. The MIMO block receives a halt request from a first core of the cores, transmits a core-halt request to one or more other cores other than the first core, to halt execution of the one or more other cores, and permits the first core to lock with a shared resource.

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: A method of generating a core dump in a User Equipment (UE) may include detecting, using at least one processor, a trigger, the trigger including an instruction to generate a core dump of the UE. The method may further include classifying, using the at least one processor, data stored in memory of the UE as Read-Write (RW) data or Read Only (RO) data. The method may further include generating, using the at least one processor, a partial core dump based on the RW data of the memory.
