本系列文章将以RTA-OS为例详细介绍AUTOSAR OS标准及概念，并分享实际使用的一些案例，本文为符合AUTOSAR标准的RTA-OS--Interrupts介绍。 中断提供了应用程序与现实世界中发生的事情之间的接口。例如，你可以使用中断来捕捉被按下的按钮，来标记时间的流逝或捕捉 ...

Just as you can often treat device registers as a memory-mapped struct, you can treat an interrupt vector as a memory-mapped array. In my last column, I suggested that you use casts sparingly and with ...

For most UNIX systems, Linux included, device drivers typically divide the work of processing interrupts into two parts or halves. The first part, the top half, is the familiar interrupt handler, ...

Performance is a topic that never strays far from the mind of most embedded systems developers. However, relatively speaking, many of us have it easy. We develop soft real-time systems in which a few ...

In a System-on Chip(SoC),a general interrupt process works as follows: Interrupt is triggered by a certain system event or interrupt source. Interrupt is detected by system’s peripheral module, which ...

This paper will discuss design practices and guidelines that will maximize the efficiency of interrupts and interrupt handling in an embedded system IC. These practices can result in a smaller code ...

This article is part of the Ideas for Design Series: Vol. 3, No. 8. In many applications, accurately sensing the position of an electrically controlled mechanical device such as a motor is critical.

Callbacks are references to executable code that higher levels of software pass into a function. These callbacks have the ability to greatly increase the portability and reuse of embedded software, ...
