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 ...

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 ...

Interruptions aren’t just a staple of our daily lives. They’re also crucial for making computer systems work as well as they do, as they allow for a system to immediately respond to an event. While on ...

In the PC, one of 256 pointers that reside in the first 1KB of memory. Each vector points to a routine in the BIOS or elsewhere in memory, which handles the interrupt. THIS DEFINITION IS FOR PERSONAL ...

A computer cannot meet its requirements unless it communicates with its external devices. An interrupt is a communication gateway between the device and a processor. The allocation of an interrupt ...

Normal execution of a given software application is contained within the bounds of one program, or instruction stream. Such execution is provable, as well as traceable. However, system designers and ...

This application note introduces the main features of the ARM Cortex-M3 processor and describes different aspects of developing software for it. It also covers the migration of existing ARM projects ...
