An Approach of Windows Memory Management Simulation on Linux

Abstract

So far open source software has been developed for several decades. Linux has gradually become one of the major operating systems. The issue that Windows application migration can be migrate to Linux is raised. However, there is great difference in the implementation mechanism between Windows and Linux. In this research, we try to build an middle layer which between application and operating system to shield the differences between the underlying operating system for the upper layer application. The middle layer provide unified fixed interface by packaging different operating system calls, so as to make the same source code can be directly translated on different operating systems with no change. It can achieve the migration of the application in source code level. In this paper, we introduce the Simulation Windows memory management mechanism. We build a Windows-like virtual memory management mechanism which simulates Windows virtual memory management on Linux. And also implement Windows heap management mechanism on Linux. And finally, two experiments are given to test and verify our approach.
