In “Handler Migration and Direct Interrupt Scheduling,” Jupyung Lee and Kyu Ho Park of the Korea Advanced Institute of Science and Technology describe two techniques to minimize the scheduling latency ...

Chris Edwards explains how interrupt handling is being offloaded from microcontrollers. For a number of reasons, including cost, embedded microprocessors have been required to take on tasks for which ...

Interrupts are a major feature of most embedded microcontrollers and effective real time response to interrupts is vital in low power systems that often rely on a ‘run fast then stop’ approach to ...

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 application note presents the RX family of microcontrollers on using multiple interrupts. The document includes the specifications, the operation confirmation conditions, the hardware and ...

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 ...

Embedded systems are deemed real-time if they will suffer a failure when a critical system event cannot be serviced in the required time, and for many embedded systems this time limit is very short.

As Arm-based infrastructure continues to scale across markets, demands on system components increase. This can mean more interrupts, or signals from hardware/software to a processor to pause a task ...

In the last lesson, you encountered the concept of a Real-Time Operating System (RTOS), and you worked out a manual procedure of switching the context from one thread to another. In this lesson, ...

For a number of reasons, including cost, embedded microprocessors have been required to take on tasks for which they are not always well suited. Frequent interruptions from the outside world is one ...
