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 ...

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, ...

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 ...

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 ...

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 ...

Endian format refers to how multibyte variables are stored in a byte-wide memory. In 'big endian' format, the most significant byte is stored in the first byte (lowest address). In 'little endian' ...

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.

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 ...

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 ...
