VAX／VMS虚实地址映射中若干算法的探讨

APPROACH TO SOME VAX/VMS ALGORITHMS OF MAPPING VIRTUAL TO PHYSICAL ADDRESSES

本文叙述了在无ＶＡＸ／ＶＭＳ操作系统支持的环境下，如何在ＶＡＸ的裸机上编写虚地址程序。也即探讨填写系统空间和进程空间页表条目（ＰＴＥ）及相关处理机寄存器内容的算法。

The paper describes how to write the virtual address programs which ran on VAX bare machines without the support of VAX/VMS operating system. In other words, the paper approaches the algorithms of filling in the system space PTE and the progress space PTE as Well as associated processor registers
