摘要

针对分布式实时系统中可扩展的操作系统架构，提出了一种动态代码绑定(DCB)方法。DCB意味着内核和服务器之间调用函数的绑定是通过函数链接表在运行时执行的，而不是传统的通过符号表的绑定方法。DCB克服了当前微内核结构中系统运行时不能更换服务器的限制，提高了系统的可扩展性和灵活性。此外，我们使用远程系统调用(RSC)在使用DCB的远程站点中执行系统原语。这是在内核级完成的，因此它提供了比用户级RPC更快和更简单的接口。因此，RSC为分布式实时系统的程序开发提供了方便。

Dynamic code binding for scalable operating system in distributed real-time systems

In this paper, we present a dynamic code binding (DCB) method for scalable architecture of operating system in distributed real-time systems. DCB means that binding for calling functions among kernel and servers is executed at run-time through function link tables, unlike traditional binding method through symbol tables. DCB overcomes the restriction that servers can not be replaced when system is running in current micro-kernel structure, therefore improves the systems' extendibility and flexibility. In addition, we use remote system call (RSC) to execute system primitives in remote sites using DCB. This is done at kernel level, so it provides more faster and simple interface than user level RPC. So RSC makes it easy to develop program in distributed real-time systems.
