摘　　要：本文基于为嵌入式系统中接口间的数据透明传输提供缓存区的建模设计的目的,采用了分层的设计方式,通过分析并定义了在数据透明传播时所需的接口间映射关系和缓存层次分类,并结合不同数据流对于其缓存区的不同需求,从最简单的数据流需求开始逐渐增加数据流需求,最终设计出一系列不同层次的缓存模型,其中着重设计了无嵌套分块缓存及可嵌套分块缓存这两种形式的缓存模型。Based on data for the embedded system provides transparent transfer interface between the buffer zone modeling design purposes, using a hierarchical design approach, by analyzing and defining the spread between the transparent mapping between the data required for the interface and cache hierarchical classification, combined with the different needs of different data streams for which the cache, from the most simple data flow demand began to increase data flow requirements, the final design of a series of different levels of caching model, which focuses on the design of the non-nested block cache and the cache can be nested block both forms of caching model.
