Abstract

Deeply embedded systems are forced to operate under extreme resource constraints in terms of memory, CPU, time and power consumption. Automotive systems are a typical example: today's limousines can be considered as (large-scale) distributed systems on wheels. There are cars in daily operation consisting of over 60 networked processors (i.e. microcontrollers). Conservative estimations suggest that, in the near future, every car will be equipped with about 20 networked microcontrollers, on average. The complexity of these "decentralized computer architectures" can no longer be managed by the application alone. Dedicated embedded operating systems are required to ensure the manageability, adaptability, portability and efficiency of the software. Resource-sparing operations under (hard) real-time constraints must be the maxim. This paper discusses the design and implementation of PURE (Portable Universal Runtime Executive) for these classes of deeply embedded systems.

PURE系列面向对象的操作系统，用于深度嵌入式系统

深度嵌入式系统被迫在内存、CPU、时间和功耗方面的极端资源限制下运行。汽车系统就是一个典型的例子:今天的豪华轿车可以被认为是车轮上的(大规模)分布式系统。日常运行的汽车由60多个联网处理器(即微控制器)组成。保守估计，在不久的将来，平均每辆汽车将配备大约20个联网微控制器。这些“分散的计算机体系结构”的复杂性不能再由应用程序单独管理。需要专用的嵌入式操作系统来保证软件的可管理性、适应性、可移植性和高效性。在(硬)实时约束下的资源节约操作必须是最优的。本文讨论了这类深度嵌入式系统的PURE (Portable Universal Runtime Executive)的设计和实现。
