We first give an analysis of the whole system and its requests for memory management Then we design and implement the memory management strategies of RTOS for this chip, including the paged virtual memory management mechanism without swap, the memory protection, the memory sharing and the static/dynamic memory allocation mechanism.
The security of file storage is one of the important research areas on information security. By combining information security technology and file storage protection of windows 2000, the aim of this paper is to study file storage protection method based on windows 2000 and is to solve the problem of file storage security.
The information security technology and file storage technology based on windows 2000 is used to design the structure and model of file storage security protection system based on windows 2000. The research is focused on the storage data encryption method based on sector and mandatory access control based on the whole storage area. File storage protection system based on windows 2000 is designed and implemented. The security of scheme and implementation is analyzed.
MASF supports a wide span of security mechanisms such as storage protection, confidentiality, authentication, integrity, authorization and security log, all these mechanisms are seamlessly integrated to secure the network management.
The article introduces a scheme of data's storage and protection in automobile data recorder. Making use of the excellent performance of Ferroelectrics RAM FM24C04 and Flash Rom AT45D081, we have solved the storage and protection problem of all kinds of dynamic data collected during the course of driving.
In this paper, we analyze the MMU supports the segment and page address-space management and protection mechanism of the IA-32 processor, discuss the design of segment unit, page unit, and the control mechanism of the MMU in pipeline. We also optimize the structure of MMU.
