摘要
在嵌入式系统中,硬件抽象层作为嵌入式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。从硬件抽象层的原理切入,介绍了基于Nexperia系列数字信号处理器嵌入式多媒体应用系统中板级支持包的实现。
As a software layer between embedded operation system and hardware in embedded system, HAL（ Hardware Abstraction Layer） is a key problem of embedded application. With the introduction of HAL theory, the BSP（ Board Support Package） which was realized in the embedded multimedia application system based on Nexperia DSP（ Digital Signal Processor） was proposed.
