Interrupt latency is one of the key factors affecting the performance of real-time systems. It refers to the time delay from when an interrupt occurs to when the corresponding Interrupt Service Routine (ISR) begins execution. High interrupt latency can lead to untimely system responses, especially in applications involving time-sensitive tasks such as embedded systems, robotics, … Read more
Introduction This article will demonstrate how to measure and visualize the real-time performance of VxWorks, explain why these measurements are important, and guide you in reproducing these tests. You will gain: • A brief explanation of why real-time performance is critical. • A reproducible test toolkit (VxWorks C language test program) to measure: • Interrupt … Read more
Hello everyone, I am Pi Zi Heng, a serious technical person. Today, I will share with you the Cortex-M System Interrupt Latency and Measurement Methods. In the embedded field, real-time performance is a concept we often emphasize. Here, real-time performance mainly emphasizes whether the system can respond within a specified time frame when external events … Read more
