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 ...

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 “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 ...

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, ...

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 ...

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 ...

If there is an interrupt present then it will trigger the interrupt handler, the handler will stop the present instruction which is processing and save its configuration in a register and load the ...

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 ...

We've seen in the previous articles how Ada can be used to describe high-level semantics and architecture. The beauty of the language, however, is that it can be used all the way down to the lowest ...
