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 ...

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 ...

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 ...

Edge-triggered interrupts are useful in microcontroller (MCU) applications for processing asynchronous events like switch closures, level transitions, and pulses. However, low-cost MCUs offer limited ...

Linux was originally written as a general-purpose operating system without any consideration for real-time applications. Recently Linux has become attractive to the real-time community due to its low ...

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 ...

Desktop or laptop computers are extremely powerful and amazingly low cost. This means that developers of software for desktop systems assume that there is infinite CPU power, so they worry very little ...

When do you need to use a real-time operating system (RTOS) for an embedded project? What does it bring to the table, and what are the costs? Fortunately there are strict technical definitions, which ...

Low-Power/High-Performance engineering sat down to discuss latency with Chris Rowen, CTO at Tensilica; Andrew Caples, senior product manager for Nucleus in Mentor Graphics’ Embedded Software Division; ...

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 ...
