Problems solved by technology
Although VxWorks, as a real-time operating system, has great advantages in national defense and industry, its high cost and relatively limited technical support hinder its wide application to a certain extent; Windows CE has a good development and debugging environment and friendly Graphical user interface has a certain market in the embedded field, but Windows CE is a non-open OS, and it is difficult for third parties to realize product customization, and copyright fees are also issues that manufacturers have to consider; on the contrary, for embedded Linux , its free, open source, strong open source community support, customizability, cross-platform, tailorable, robust and stable features make it occupy a large proportion in embedded operating systems

The invention discloses a disk I / O (Input / Output) test system oriented to an embedded system. The disk I / O test system comprises a client side and a target machine side, wherein the client side is in network connection with the target machine side. The client side comprises a transmission control module, a data processing module and a display switching module; and the target machine side comprises a test agent module and a test execution module. The disk I / O test system has the beneficial effects of testing the I / O performance of an embedded disk in special systems, monitoring the disk I / O of the system in real time and analyzing whether a bottle neck exists in the I / O, monitoring the I / O condition of processes in real time and obtaining the disk I / O access condition of the software running in the system in real time, tracking and recording each disk I / O access, and storing the records in a database. On one hand, a drive layer monitors the disk I / O; and on the other hand, the collected daily reading and writing data can be used as an input source in the disk test so as to simulate the practical application, and finally, true and reliable performance assessment on the tested disk is obtained.
Description
technical field [0001] The invention relates to the technical field of information storage, in particular to a disk I / O test system for embedded systems. Background technique [0002] With the rapid development of the information age in which computer technology and communication technology are combined, the integration trend of 3C (namely, computer, communication, and consumer electronics) is becoming more and more obvious. Embedded system has become an ideal carrier of 3c integration by virtue of its own characteristics, so the research and development of embedded system has become a hot spot at present. The information age has higher and higher requirements on the memory performance and capacity of the embedded system, unlike the early embedded systems that have no external memory or only simple external storage devices. Disks have been gradually introduced into embedded systems. The innovation of disk technology, especially the production of micro disks, makes disks bou...
