摘　　要：新一代导弹任务计算机拟采用综合模块化航空电子体系。该体系能够将传统的多个子系统综合到单一的硬件平台。为此文中提出了一种强分区操作系统模型,该模型能够提供各应用分区在时间和空间上完全的独立和隔离。文中着重就强分区内核FCOS的体系结构、分区调度、分区间通信以及存储管理等进行了详细的论述,并对该操作系统进行了评估和优化。最后结合某型弹载武器系统,使用该操作系统将传统上独立的三个子系统综合到一个系统中。The new missile task computer system employs the architecture of integrated modular avionics. Based on this architecture, the traditional sub-systems will be integrated into a single hardware platform. In this paper, a strong partitioned operating system model was proposed. With this model, the software platform can guarantee that every partition is completely independent and isolated from others. The strong partitioned operating system kernel FCOS was discussed in detail, including system architecture, partition scheduling, inter-partition communication and memory management. Besides, the analysis and evaluation of this kernel FCOS base on different benchmark were con- ducted. In terms of results, an optimized memory management was mentioned as well. As a real case, an integrated missile task system with three traditional systems integrated into one platform was illustrated.
