摘要

In this paper,we first analyze datastorage models in typical operating systems,the re-lation between distributed shared memory and datastorage model,as well as the relation between mem-ory hierarchy and data storage model.Then we pro-pose the concept of No Address Space Operating Sys-tem,discuss an implementation prototype,and ana-lyze its performance and advantages.We believe thatthe concept of process virtual address space should beabandoned in operating systems,instructions shouldaccess files directly,and processes should run on files.Compared with other operating systems,No AddressSpace Operating System has many advantages andshould be adopted in computer systems.
