Abstract

The present invention relates to a software structure for implementing to record high-speed real time data, in particular to a software structure for small computer system interface (SCSI) device. The structure includes a file management module for user's operation capable of directly reading/writing a SCSI function library, a SCSI card and a SCSI device. The SCSI device can be controlled by directly reading/writing the SCSI function library so as to be free from the limitation of the operating system, making the performance of the SCSI device to the utmost. Besides, a function library similar to general file function is provided and the corresponding file management module having graphical user interface is created to simulate the operation and utilization of regular file. As a consequence, it is unnecessary for user to learn again for immediately employing the file management module to browse the data stored in the SCSI device.

1235327 V. Description of the invention (2). :: Sister's current data recording or transfer procedure is generally handled by the file system provided by "k". Because of the "low;" cache system of 32), the speed provided by the streamlining will be measured, even if s, n are used. : 丄 0Mb yt ...... The speed of the left and right = In the shell material acquisition or measurement application (such as: high-speed remote system 2 control system ... etc.), it must be fast and reliable data = storage device to Facilitate post-mortem analysis or: The above-mentioned d-recording or transmission procedures are no longer sufficient, and related industries have developed this kind of data storage card, which has been stored in direct memory (Di rect Memory)

Access DMA) access method, the data retrieved by data retrieval is directly stored in the data storage device, so the data retrieved by the high-speed data retrieval device can be recorded on the data storage device. The method still has the following disadvantages: ( A) The cost of data storage cards is quite expensive, and the selling price is tens of thousands of consumers' low willingness to buy. (1) The data saved by using the memory card cannot be read directly under normal operations, and the data must be taken out by the manufacturer before use, and this function can only be read and modified> Materials' and cause inconvenience in use. It is based on 'how to solve the above problems, that is, the speed hard disks that are engaged in the operating system and files of this line, and the control system is a large number, so the solution is to unlock the card for the device.' This kind of function can't be matched with a unified function.
