| Abstract: | 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. |
