本文主要是介绍K210 FreeRTOS多任务多核系统调度，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
一、目的
众所周知，K210这款AI新品是一款64bit 双核芯片，其支持裸机编程，并且官方也提供freertos sdk，方便开发者在其上进行多任务应用开发。那么如何进行任务创建和多核开发呢。
二、参考
#include <stdio.h>
#include "FreeRTOS.h"
#include "task.h"static void task_0(void *args) {while (1) {printf("task 0 on core %d is polling\n", (int)uxPortGetProcessorId());vTaskDelay(1000 / portTICK_PERIOD_MS);}vTaskDelete(NULL);
}static void task_1(void *args) {while (1) {printf("task 1 on core %d is polling\n", (int)uxPortGetProcessorId());vTaskDelay(1000 / portTICK_PERIOD_MS);}vTaskDelete(NULL);
}int main() {printf("Hello K210!!!\n");//在core 0上创建一个优先级为5的任务task_0xTaskCreateAtProcessor(0, task_0, "task0", 1024, NULL, 5, NULL);//在core 1上创建一个优先级为5的任务task_0xTaskCreateAtProcessor(1, task_1, "task1", 1024, NULL, 5, NULL);while (1) {printf("main on core %d is polling\n", (int)uxPortGetProcessorId());vTaskDelay(2000 / portTICK_PERIOD_MS);}
}
在上一篇博文中，我们已经介绍过，main函数是freertos在core 0上创建的一个线程，构建烧写后从日志上可以看到跟预期一下。

Hello K210!!!
task 0 on core 0 is polling
task 1 nocer0 i polling
g
task 0 on core 0 is polling
task 1 on core 1 is polling
task 0 on core 0 is polling
main on core 0 ta ko1lon
ore 1 is polling
task 0 on core 0 is polling
task 1 on core 1 is polling
task 0 on core 0 is polling
main on core 0 is polling
task 1 on core 1 is polling
task 0 on core 0 is polling
task 1 on core 1 is polling
task 0 on core 0 is polling
main on core 0 is polling
task 1 on core 1 is polling
至此，一个最简单的多任务多核应用介绍结束。
