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 ...
When debugging something as involved as kernel scheduler timings, you would typically use one of the software-based debugging mechanisms available. However, in cases when software is close to bare ...
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 ...
An embedded system typically has enough CPU power to do the job, but typically only just enough — there is no excess. Memory size is usually limited. It is not unreasonably small, but there isn't ...
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 ...
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; ...
There's an interrupt service routine invoked when the 16 bithardware timer overflows. The ISR services the hardware, increments aglobal variable named timer_hi, and returns. Therefore, timer_hi ...
The time it takes to service an interrupt. It becomes a critical factor when servicing real-time functions such as a communications line. See UART overrun. THIS DEFINITION IS FOR PERSONAL USE ONLY.
