摘要： 垂直迁移是改善软/固件分层系统性能的有效技术。为了取得系统的全局性能改善,必须将一些功能迁移到固件层,只迁移少数几个功能是远远不够的。本文在分析了各种垂直迁移方式之后,提出了采用这些方式的混合形式作为典型的复杂多分层系统 RDBMS的迁移方法,以使更多的功能可被迁移。文中对候选迁移功能的选择以及它们对其他软件功能的过程调用问题进行了详细的讨论。文章最后讨论了实现垂直迁移所需要的环境支持。

Abstract: Vertical migration is an effective technique for improving the performance in layered software/firmware systems. For global performance improvement, it is not enough to migrate a few functions but a set of functions. This paper gives an analysis of the migration types and suggests a hybrid of these types as the migration approach to a typical complex multi-hierarchy system RDBMS, by which more functions can be migrated. The candidate selection and procedure calls by candidates for other software modules are discussed. Finally, the environment to support migration of RDBMS functions is described.
