Abstract
The present invention provides a data acquisition interface of a memory device, namely a small computer system interface (SCSI) interface, which relates to a data acquisition technique. The interface is composed of a central processing unit (CPU), a decoding circuit, a control interface, a data interface, a data sequence circuit and an SCSI memory device. As a microcomputer and an SCSI adapter in an original SCSI interface are cancelled, the interface has small volume and strong anti-interference capability. The intermediate link of data circulation is reduced, and acquisition speed is high. The present invention is a data acquisition system for large-capacity magneto-optical discs and SCSI hard discs, which has the advantages of low price and simple operation.
Description
The present invention relates to data acquisition technology.
Used small-size computer data acquisition interface (Small Computer System In-terface is called for short scsi interface), day by day become the standard interface of digital implementation and mass-memory unit, the magneto-optical disk storage systems that particularly has SCSI bus, it is big, easy to carry and do not have advantages such as wearing and tearing to have memory capacity, and become the main memory device of computer system gradually, also be used widely at aspects such as data acquisition, audio-video signal processing.And in the existing magnetic optical disk data acquisition system, be the SCSI memory device to be linked to each other with microcomputer by scsi adapter.Data acquisition channel machine internal memory as calculated arrives SCSI memory device (see figure 1) again to scsi adapter.Like this intermediate link of data circulations many, cause picking rate not high, again because the participation work of computing machine is arranged, thereby scsi interface is cost an arm and a leg, volume is big, be subject to interference, system reliability is not high.
The objective of the invention is to reduce the interference in the work in order to improve picking rate, improve the reliability of system works and the cost that reduces equipment, the spy has carried out new design to the scsi interface circuit.
The present invention realizes by following design proposal, original scsi device includes microcomputer, scsi adapter and SCSI memory device, the present invention is with original microcomputer and scsi adapter, with microprocessor (cpu), decoding scheme, control interface, the circuit that data-interface and data time sequence circuit constitute replaces, and microprocessor (cpu) adopts the single-chip microcomputer (see figure 2).Its groundwork principle is to press the contact of SCSI agreement by microprocessor (cpu) and SCSI memory device, and control data interface and SCSI memory device carry out exchanges data again.Realize the high-speed real-time read/write.As adopt high speed microprocessor (cpu), and also can be with external data reading into the microprocessor (cpu), being encoded writes the SCSI memory device again, passes out to the outside after decoding when reading again, and can add error correction and timing code function like this.Enlarge using value.
The present invention has reduced the volume of equipment owing to adopt single-chip microcomputer to replace computing machine, has reduced cost, factor arrives the SCSI memory device according to only gathering through interface again, has reduced the middle flow link, has accelerated acquisition speed, and reduced interference, thereby improved the reliability of work.The present invention can insert International Business Machines Corporation (IBM) and compatible thereof with the plate form in addition.
Description of drawings:

Fig. 2-functional-block diagram of the present invention
2 further specify the present invention in conjunction with the accompanying drawings.
Microprocessor (cpu) sends order by control interface to the SCSI memory device, and the state that reads back, information, control and prison show SCSI memory device read/write data, read/write data writes and reads the SCSI memory device via data-interface, the data time sequence circuit produces the control external data source and writes/sense data interface and control data interface and SCSI memory device between swap data.Decoding scheme produces the port control signal of total system.
Claims (2)
1, a kind of data acquisition interface of memory device, be by microprocessor (CPU), decoding scheme, control interface, data-interface and data time sequence circuit constitute, the data acquisition system (DAS) that can form with the write-read type memory device of band scsi interface, the microprocessor (CPU) that it is characterized in that this data acquisition interface sends order by control interface to memory device, and the state that reads back, information, control and supervision memory device read/write data, data write and read memory device via data-interface, the data time sequence circuit produces the control external data source and writes/sense data interface and control data interface and memory device between swap data, decoding scheme produces the port control signal of total system.
2,, it is characterized in that microprocessor (CPU) is to adopt single-chip microcomputer according to right 1 desired data acquisition interface.
