Separating Data Storage, Data Computation, and Resource Management One from Another in Operating Systems

摘要

It's impossible for traditional operating systems to separate the abstract for data storage (process virtual address space), the abstract for data computation (thread), and the abstract for resource management (process itself) one from another. In this paper, firstly we analyze the problems due to not separating these three abstracts. On the basis of the analysis, we propose the idea that these three abstracts should be separated, and on the basis of the idea, we propose Operating Systems Basing Virtual Address Spaces on Files (OS-BVASF). Then we investigate OS-BVASF architecture model, Thread Migration and Instructions Accessing Files Directly that implement the separation. In the end of this paper, we discuss its implementation and performance test.
