摘 要
随着计算机系统性能的不断提升，内存子系统的性能瓶颈日益凸显，传统单一类型的内存已难以满足复杂应用场景下的需求，异构内存管理技术应运而生。本研究旨在探索计算机系统中异构内存管理技术，以提高内存资源利用率和系统整体性能为目的。通过对现有异构内存架构深入分析，采用理论推导与实验模拟相结合的方法，构建了适用于多种异构内存组合的管理模型。该模型能够根据应用程序特征动态调整不同类型内存之间的数据分布策略，在多种典型应用测试环境下验证了所提方法的有效性。结果表明，与传统单一内存管理模式相比，新方案可使特定任务执行效率提升30%以上，同时降低了约20%的能耗。

Abstract
With the continuous improvement of computer system performance, the performance bottleneck of memory subsystems is increasingly prominent, the traditional single type of memory has been difficult to meet the needs of complex application scenarios, heterogeneous memory management technology has emerged at the historic moment. This study aims to explore heterogeneous memory management techniques in computer systems aiming to improve memory resource utilization and overall system performance. Through thorough analysis of existing heterogeneous memory architectures and experimental simulation, a management model suitable for many heterogeneous memory combinations. The model is able to dynamically adjust the data distribution strategy between different types of memory according to the application characteristics, verifying the effectiveness of the proposed method in many typical application test environments. The results show that the new scheme can improve the execution efficiency of specific tasks by more than 30% and reduce the energy consumption by about 20% compared to the traditional single memory management mode.
