RT FIFO函数用于在VI之间以确定性方式发送和接收数据。RT FIFO函数的确定性数据传输不会向实时VI增加抖动。RT FIFO不是一种严格的通信方式,当FIFO被填满后,旧数据会被新数据覆盖。范例该选板上的函数返回一般LabVIEW错误代码或RT FIFO特定错误代码。注: 如使用RT FIFO传输波形数据,由于变体的大小由变量确定,与RT ...

FIFO的分类根均FIFO工作的时钟域,可以将FIFO分为同步FIFO和异步FIFO。同步FIFO是指读时钟和写时钟为同一个时钟。在时钟沿来临时同时发生读写操作。...异步FIFO是指读写时钟不一致,读写时钟是互相独立的。 FIFO设计的难点 FIFO设计的难点在于怎样判断FIFO的空/满状态。

借助调度类的框架,这些实时策略并不被完全公平调度器来管理, 而是被一个特殊的实时调度器管理。具体的实现定义在文件kernel/sched_rt.c中,在接下来的内容中我们将讨论实时调度策略和算法 一、SCHED_FIFO SCHED_FIFO实现了一种简单的、先入先出的调度算法:它不使用时间片 ...
I have noticed that, for the RT1021, the LPUART FIFO[RXUF] flag (Receiver FIFO Underflow Flag) seems to always be set to 1.I have also noticed that the driver fsl_lpuart.c does not observe it (blocking or non-blocking), although it does allow you to enable the interrupt and...
Hi all, I'm setting the LPUART FIFO RX and TX sizes and it only seems to be 4 words and cannot be set to any other value. In the RM it says maximum
