摘　　要：综述了嵌入式数据库缓存技术的发展现状,分析了目前较为常用的缓存替换算法,基于农业设备的嵌入式数据库这个特定应用领域,结合其特点提出了一种缓存块大小可变的缓冲管理结构和基于CLOCK替代策略的专用缓冲管理机制。详细阐述了该缓存管理器的设计思路和具体实现细节。In this paper, the development status of the embedded database caching technology was described, and some common used buffer replacement algorithms were analyzed. Based on the embedded database of agricultural device and combined with its own characteristics, a new buffer management module was proposed, which had variable cache size and applied CLOCK buffer replacement algorithms as its alternative strategy. Furthermore, the design ideas and the specific implementation details were described.
