rt_pin_attach_irq函数是嵌入式系统中实现外部中断响应的关键函数之一。通过将引脚与中断服务程序关联起来,可以实现对外设中断的处理。在使用该函数时,需要注意中断服务程序的执行时间、触发方式的设置以及引脚的稳定性等问题。通过合理地使用rt_pin_attach_irq函数,可以实现对外部中断的有效响应,提高系统的实时性和可靠...

NUMA 架构中,内存访问有远近之分,只有当 CPU 访问自身直接 attach 内存对应的物理地址时,才会有较短的响应时间(Local Access)。而如果需要访问其他 CPU attach 的内存的数据时,就需要通过 inter-connect 通道访问,响应时间就相比之前变慢了(Remote Access),NUMA(Non-Uniform Memory Access)就此得名。 --- 引自...
