Embedded systems rely on interrupts to tell a processor when something needs service. Often, the system's response time to an interrupt is critical to proper operations. To learn how well your ...

The sequence of importance assigned to interrupts. If two interrupts occur simultaneously, the interrupt with the higher priority is serviced first. In some systems, a higher-priority interrupt can ...

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 ...

What’s the biggest difference between writing code for your big computer and a microcontroller? OK, the memory and limited resources, sure. But we were thinking more about the need to directly ...

Whether an embedded system is a handheld Internet device, a telephone switch, or a complex aircraft control setup, the real-time operating system (RTOS) running it must guarantee uninterrupted service ...

As a fully preemptive kernel, SST must ensure that at all times the CPU executes the highest-priority task that's ready to run. Fortunately, only two scenarios can lead to readying a higher-priority ...

From the humble infinite loop to the priority-based preemptive RTOS and beyond, scheduling options are everywhere to be found. This article offers a survey and comparison. Many different kinds of task ...

October 31, 2013-- Digital Core Design, IP Core provider and the System on Chip design house from Poland introduced in its offer the D8259. DCD’s Programmable Interrupt Controller is fully ...
