Abstract

With the rapid development of information technology, multi-core processors have become the core force driving the improvement of computing performance. This article starts from the architecture of multi-core processors and explores in depth their performance advantages, parallel computing foundations, resource scheduling, task scheduling and load balancing, cache consistency and memory management, and other key areas. It also focuses on analyzing optimization strategies for multi-core processor architectures. Firstly, the background and significance of the research were elaborated, and a review of the current research status at home and abroad was conducted, with the research ob jectives clearly defined. Subsequently, the development history, basic structure, and performance advantages of multi-core processors were outlined, with performance advantages including improved processing speed, enhanced multitasking efficiency, and reduced energy consumption and thermal design power. On the basis of parallel computing, the article further discusses the principles, models, efficiency, and scalability of parallel computing. In terms of resource scheduling, the resource allocation strategy, scheduling algorithm, and application of virtualization technology were analyzed. In terms of task scheduling and load balancing, optimization methods for task scheduling and the importance of load balancing were proposed, and real-time scheduling and performance prediction were discussed. In addition, in-depth analysis has been conducted on cache consistency issues, cache optimization techniques, and memory hierarchy and access optimization. In the optimization strategy of multi-core processor architecture, detailed explanations were given from the aspects of hardware and software parallelization design, task granularity control and load dynamic adjustment, as well as dynamic power management and energy consumption optimization. Finally, this article summarizes the main conclusions of multi-core processor architecture optimization, providing theoretical guidance and practical references for the future development of multi-core processors.
