Abstract: A method and system for providing memory management in a Real-Time Operating System (RTOS) based system are provided. The method includes creating a plurality of tasks with a two level stack scheme comprising a first level stack and a second level stack, scheduling a first task for execution by moving a stack pointer from the first level stack to the second level stack, determining whether the first task is pre-empted, allocating the second level stack to the first task in a second state if the first task is not pre-empted, changing an active task for execution, determining whether the first task relinquishes control from the second state and is waiting for a resource, moving the stack pointer back from the second level stack to the first level stack if the first task relinquishes itself and providing the second level stack for use by a second task.

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.
