The invention discloses an RTOS-based SMP scheduling method and system. The method comprises the following steps that: 1, a data collection module collects task name data, task state data in a CPU, task priority data, task binding data, urgent task name data, urgent task binding data and urgent task priority data, transmits the task name data, the task state data in the CPU, the task priority dataand the task binding data to a data analysis module, transmits the urgent task name data, the urgent task binding data and the urgent task priority data to a scheduling module; and step 2, the data analysis module performs analysis operation on task information and urgent task information. Through the arrangement of the scheduling module, the urgent task information is analyzed and compared withdata running in the CPU, so that tasks are scheduled, and therefore, timely processing of urgent tasks is guaranteed, scheduling stability is improved, and scheduling work efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of SMP scheduling, in particular to an RTOS-based SMP scheduling method and system. Background technique [0002] Symmetrical multiprocessing, referred to as SMP, refers to the collection of a group of processors on a computer, and the shared memory subsystem and bus structure between CPUs. It is a parallel technology that is widely used in comparison with asymmetric multiprocessing technology. [0003] The SMP scheduling method currently used on TROS is described as follows: each core of the multi-core processor is independently scheduled and interrupted independently, and each core has its own private priority ready queue, which is used for task scheduling bound to the core. , each core shares a global priority ready queue, which is used for task scheduling of unbound cores; when scheduling, the core will find the task with the highest priority from the global queue and private queue for scheduling, and th...
