基于东芝单片机的嵌入式系统硬件抽象层实现

Realization of Embedded System HAL Based on Toshiba SCM

嵌入式系统是将先进的计算机技术、半导体技术和电子技术以及各个行业的具体应用相结合后的产物,这一点就决定了它必然是一个技术密集、资金密集、高度分散、不断创新的知识集成系统.硬件抽象层作为操作系统和硬件之间的软件层次是嵌入式应用的一个关键问题.本文从硬件抽象层的原理入手,给出了作为嵌入式系统中硬件抽象层的实现形式BSP(板级支持包)功能和特点,并提供了基于东芝单片机的设计实例.

Embedded system results from computer technique,semi-conductor technique,electronics technique and actual application of various professions,which determined it a knowledge integrating system of technique intensive,funds intensive,high deconcentration and perpetual innovation.As a software layer between operation system and hardware,HAL is a key problem of embedded application.The thesis starts from HAL theory,introduces the function and characteristics of BSP which is the realization form of HAL of embedded system and brings up the actual designed example based on Toshiba SCM.
