摘　　要：主要讨论了现代医疗仪器用多微处理器操作系统体系结构 ,并详细介绍了一个原型系统的设计与实现 .多功能、多参数、智能化、网络化是现代医疗仪器系统的发展方向 .为了给这种趋势提供一种更好的软硬件支撑环境 ,我们研制了现代医疗仪器用多微处理器系统 .与共享存储型的紧耦合系统相比 ,分布式存储型的松耦合体系结构具有性能价格比高、可靠性好、增量可扩充性强以及满足内在分布式应用等优点 ,它代表了未来医疗仪器系统的发展趋势 .在此硬件平台上构造了一个适用于现代医疗仪器的弱实时分布式操作系统 ( IOWRTDOS) .由于其体系结构综合了层次模型和微内核模型 ,分析与设计采用面向对象技术 ,因而系统具有结构灵活、模块性好、易于移植和自由扩充等特点 .The operating system architecture and the implementation of a prototype system were studies and discusse in detail. The directions of modern medical instrument system are multi\|function, multi\|parameter, intelligence and network. To provide a more excellent hardware and software supporting environment for this trend, we develop a modern medical instrument\|oriented multiprocessor system. Compared with the closely\|coupled system that has shared memory, the loosely\|coupled architecture with distributed memory has many advantages such as good performance\|price ratios, higher reliability, incremental growth and satisfying distributed application inherently. It represents the developing trends of the future medical instrument system. Based on this hardware, we construct a modern medical instrument\|oriented weak real\|time distributed operating system (IOWRTDOS). Because the system integrates hierarchical model and microkernel model in the architecture design and takes object\|oriented technique during the analysis and implementation, it is characterized with the flexible architecture, excellent modularity, easy portability and free extensibility.
