Description
Technical field
The present invention relates to a kind of system and method for realizing at a high speed instant data recording, relate in particular to a kind of system that is used in minicomputer system interface (SCSI) device, but the format library at utilization direct read minicomputer system interface (SCSI), to break away from the management of operating system to file, and then the data of direct access minicomputer system interface (SCSI) device, it is ultimate attainment that hard disk usefulness is performed to.
Background technology
Computing machine science and technology is grown up with the speed of making rapid progress now, the development trend of its computing machine also reaches fireballing direction by force towards calculation function and strides forward, and motherboard and relevant peripherals (as hard disk, CD-ROM drive) etc. are when connecting, and needing one can be for the interface of definition of data transmission.Personal computer adopts SCSI (minicomputer system interface) one after another in recent years, a slice SCSI adapter is looked different form, can connect at most and connect in seven, 15 or 31 ones and external scsi device, and can comprise magnetic tape station (TAPE DEVICE), hard drives (HARD DISK), scanner (SCANNER), Magneto Optical MO (MO), cd-ROM (CD-ROM), digital audio tape (DAT), cd-recorder (CD-R, CD-RW, DVD-ROM, DVD-RAM) etc.Use the SCSI card can reach the 80Mbytes/sec except transmission speed, because its unique design, make that the burden of central processing unit is less, transmission usefulness is also comparatively stable, this is for scanner that needs stable transfer or cd-recorder, be a crucial characteristic, also therefore these equipment are unique interface with the SCSI interface mostly.
Yet, at present the program of data recording or transmission generally is to handle via operating system and the file system that provided thereof, because the restriction (as: MS-DOS is to the restriction of 2-Gbytes, the fast taking system of Win32) of these operating systems and file system can make the speed of record or transmission data far below the speed that bus provided, even use the also maximum speed that only can reach about 10Mbytes/sec of SCSI hard disk.So, (as: high-speed remote control system, embedded control system in some data acquisitions or metrology applications ... Deng), just must be fast and reliably mass data is recorded storage device, in order to carrying out analysis afterwards or processing.So, above-mentioned record or transmission procedure have not just applied and have used, then the step is developed a kind of data storing card and relevant dealer is for head it off, this kind data storing cartoon is crossed direct memory (Direct Memory Access, DMA) mode of access, the data that data fatching apparatus captured directly are stored in data memory device, thus can be at high speed data recording that data fatching apparatus captured to data memory device, but this kind way still has following shortcoming:
(1) cost of data storing card is quite expensive, and price is hundreds thousand of easily, the purchase intention of incompatibility ordinary consumer.
(2) use the stored data of data storing card, under general operating system, promptly can't directly read, must be again data be taken out and just can use, and this kind form only can read and can not revise data, and cause the inconvenience in the use via the form that manufacturer provided.
Thus, how to address the above problem, be the relevant manufacturer that is engaged in the industry and desire most ardently the improved direction of research place.
Summary of the invention
Fundamental purpose of the present invention is, a kind of system that realizes at a high speed instant data recording is provided, the format library of this system direct read minicomputer system interface but (SCSI), break away from operating system and file system and come directly the SCSI device to be carried out access, ultimate attainment in order to hard disk usefulness is performed to.
