摘要
由于常用的嵌入式操作系统不能很好地适用于智能仪器仪表小内核、高实时、高可靠的要求,本文针对智能仪表对嵌入式操作系统特殊要求,通过分析常见嵌入式操作系统的任务调度算法,提出了一种新的应用于智能仪表的实时任务调度算法。并在典型的8位、16位SOC上进行设计和实现了基于这种算法的嵌入式操作系统。
The generic embedded operating system can not meet the requirement of little kernel, high real time, high reliability about intelligent instrument, This paper aim to resolve the especial requirement of intelligent instrument to embedded operating system, give a brief introduction about the task schedule arithmetic in common embedded operating system. Then put forward a new task schedule arithmetic used in the intelligent instrument. Based on this arithmetic design and implement an embedded operating system on typical 8 bit and 16 bit SOC as well.
