Abstract

As industrial automation advances, the real-time performance of embedded systems has become crucial for ensuring the efficient and stable operation of industrial production. Thanks to their compact size, low power consumption, and strong performance, embedded systems are widely used in industrial automation control. However, real-time performance faces numerous challenges. This paper elucidates the concept of real-time performance in embedded systems, analyzes how hardware architecture, operating systems, and task scheduling impact real-time performance, and explores methods to enhance real-time performance, such as hardware optimization, operating system selection, and improvements in task scheduling algorithms. Through theoretical analysis and technical research, this paper aims to provide a reference for achieving higher levels of real-time performance in industrial automation control using embedded systems, thereby promoting the development of industrial automation towards smarter and more efficient directions.
