摘要
通过分析现有嵌入式系统I/O驱动的各种方法和模式及其优缺点,提出了一种核外I/O技术与分层思想相结合的I/O驱动模式,使得I/O驱动结构清晰、代码实现容易,跟踪调试方便并能很好的隐藏硬件驱动细节同时具有较好的实时性,代码在基于SHARP的S1C33L11处理器的SMARTPHONE上得到验证。
This paper first analyzed advantage and disadvantage and the method of I/O Device Driver model based on Embedded Operating System. It discussed user-level I/O Technology of process structure combining with layered structure model which results in legible I/O device driver structure and code-written-easily and it is convenient for Debug and concealing hardware driver detail and upstanding real-time. Its code was testified in SMARTPHONE with sharp SIC33Lll CPU.
