嵌入式系统底层软件结构模型建构与协同性分析

Set-up and Analyzing the Module of the Embedded Bottom Software the System Structure and the Cooperativity

从探讨嵌入式系统结构和协同性角度出发,分析了嵌入式系统是否采用操作系统的原因以及与硬件层密切相关的嵌入式系统底层启动加载软件Bootloader和板级支持包软件BSP的特性分析,给出相关模型、协同性设计流程、Bootloader以及BSP主要过程。为嵌入式系统的设计与应用提供有益的帮助。

From the structure and cooperativity of the embedded system,analyzed the reasons that the embedded system have or not the operation system,and summarized performances of the bootloader and the bsp.The start-up and loading software （bootloader） and the board support package （bsp） related to the bottom hardware closely is the base of the embedded system.And gave main system models and a cooperative flowchart,and gave the main designing processes of the bootloader as well as bsp.So that help to design and apply the embedded system.
