FreeRTOS 的组件包括调度器,内存管理单元及任务间通讯方法,当然还提供可选的软件定时器(事 实上,多数 RTOS 提供的组件都是这几项)。因此对 RAM 的使用情况的评估也与这几项直接相关。内 存管理单元提供内存管理办法,直接消耗内存的包括调度器,任务间通讯方法及软件定时器,当然每 一个任务还需要一定的堆栈空间。在具体的应用中,使用的任务数量可能不同,每个任务的堆栈空间 也可能不一样,任务间通讯的方式也可能不同,当然我们还要考虑到MCU 得内核和编译器优化选项的 问题。但是,通过简单的估算,还是可以轻松的得到 RAM 使用情况的大体信息。 文中提供的信息是以 STM32F407(Cortex-M4 内核)为硬件,IAR 编译选项开到最高,FreeRTOS 采 用最新的 v8.0.0 来进行测试的
