By analyzing the function structure of mass storage system comprehensively, we decompose the whole system into some single equipment by its own function. Then analyze the device working principle to analysis and description the method of equipment energy consumption. And according to the result, test the cluster system in the lab environment.

Recently, flash memory is becoming a popular data storage device in most of the electronic consumer devices. It has lots of attractive features such as small size and light weight nature, zero noise, solid-state reliability, low power consumption, and better shock resistant. To make it suitable for real-time embedded applications, this paper presents the design of an object based file system that uses parallel operations to guarantee bounded read-write access latencies to real-time tasks, in the presence of requests from non real-time tasks. The proposed scheme requires minimal support from the underlying operating system.

In many safety-critical missions, more and more Multiprocessor Embedded Systems are used to provide the ability of fault tolerance. Using Operating System can easy software design and make software development more efficient. Because of the limited resource in Embedded Systems, many advanced technologies used in common desktop multiprocessor environment have not been used in Embedded RTOS yet. In this paper, we introduce the technologies of Virtual CPU Pool and Multiprocessor Processor Communication Interface to solve task distributing and communication between deferent CPUs. After using and mending uC/OS, I finally realize and test an Operating System in a kind of SMP multiprocessor hardware module successfully.

Researches on technologies about testing aggregate bandwidth of file systems in cloud storage systems. Through the memory file system, network file system, parallel file system theory analysis, according to the cloud storage system polymerization bandwidth and concept, developed to cloud storage environment file system polymerization bandwidth test software called FSPoly. In this paper, use FSpoly to luster file system testing, find reasonable test methods, and then evaluations latest development in cloud storage system file system performance by using FSPoly.

RFID (Radio Frequency IDentification) technology has been widely used in many applications. In recent years, researchers have begun to study various RFID data management problems. Unfortunately, it is difficult for researchers to obtain massive raw RFID data because of hardware cost and limitations of lab environment. We have designed RFIDTango, a massive raw RFID data generator, to simulate real RFID application scenarios. In this paper, we present a system of RFIDTango and show how RFIDTango can simulate a RFID-enabled supermarket scenario effectively and efficiently.
