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, ...

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' ...

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 ...

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 ...

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, ...

A technical paper titled “CV32RT: Enabling Fast Interrupt and Context Switching for RISC-V Microcontrollers” was published by researchers at ETH Zurich and University of Bologna. “Processors using the ...
