摘要

为了满足上市时间的要求,改进系统设计效率是至关重要的。通过利用可重用的设计方法,有可能满足项目管理需求。由于并发性问题,组件集成经常会失败。这些并发性问题主要发生在组件同时访问共享资源并相互通信时。如果这些问题得不到解决,那么系统可能会导致零星的灾难性故障。在本文中,我们提出了一种从需求文档中开发并发兼容组件的方法。我们已经将这种方法应用于开发实时操作系统(RTOS)的进程管理和内存管理方面。

Concurrency Compliant Embedded System Modeling Methodology
To meet time-to-market demands, it is crucial that improvement be made to the system design efficiency. By utilizing a reusable design methodology, it is possible to meet project management requirements. Component integrations may often fail due to concurrency concerns. These concurrency problems mainly occur when components access share resources simultaneously and communicate with each other. If these problems are not addressed then a system could lead to sporadic and disastrous failures. In this paper, we propose a methodology for developing concurrency compliant components from a requirements document. We have applied this methodology to develop process management and memory management aspects of a Real Time Operating System (RTOS).
