An RTOS includes an event processor construct. The event processor has a task priority and an event processor handler. A stack for the event processor is allocated by the RTOS. The event processor handler is called by the RTOS each time an event is posted by an interrupt request handler or another task. Once processing of the event completes, the event processor handler returns (as opposed to remaining in an infinite loop) thereby allowing the stack allocated to the event processor to not be retained on entry into a sleep state and the memory bank containing the stack to be powered down during a sleep state.

The present application belongs to the technical field of embedded real-time system, and particularly relates to a non-hungry distribution method of multi-core processor based on EDZL algorithm. The method comprises the following steps: firstly, obtaining a real-time task set by calling system parameters, and calculating the priority of each task in the task set; secondly, calculating the slackness of each task, setting the priority of the task with zero slackness as 0, and arranging the tasks into a stack according to the priority from high to low; and finally, distributing the task set to the processor cluster by using the non-hungry processor distribution method. The method has good applicability, can improve the system resource utilization rate of the processor, balance the system performance and task power consumption, and effectively guarantee the real-time performance of the system.

Apparatuses, methods, and systems are disclosed for setting up multiple user plane (“UP”) security contexts. One apparatus includes a transceiver and a processor that derives distinct UP integrity and ciphering keys for a selected central unit user plane (“CU-UP”) node in the RAN, said derivation using a key derivation function. The processor assigns a UP Security Indicator to uniquely identify the derived distinct UP integrity and ciphering keys and the transceiver sends a setup request to the selected CU-UP node, said setup request containing the UP Security Indicator and the distinct UP integrity and ciphering keys. The transceiver receives a setup response from the selected CU-UP node and the processor activates distinct UP security at a UE.

A technique for allocating registers to a processor is provided. The technique includes identifying a first instruction in an instruction dispatch set that satisfies all register allocation suppression criteria of a first set of register allocation suppression criteria, suppressing register allocation for the first instruction, identifying a second instruction in the instruction dispatch set that does not satisfy all register allocation suppression criteria of a second set of register allocation suppression criteria, and allocating registers for the second instruction.

An operating system running data collection method and an electric device. The operating system running data collection method comprises: allocating a ring buffer for a processor in a memory, and at least one event is recorded in the ring buffer; stopping recording and saving at least one event generated later than a reference time; wherein the reference time is the latest time of a first event. The scheme no longer needs periodic resource occupation, reduces the influence on service performance; at the same time, the latest time of the first event recorded in the ring buffer is taken as the reference, and events earlier than the time point are removed, so that the analysis exception caused by the loss of buffer data is avoided, and the data time window consistency is ensured; the scheme does not need to allocate a central buffer storage area, and the occupation of too much system memory is avoided.
