The invention relates to a mass data storage control module and belongs to the technical field of application of photoelectric products. The mass data storage control module can control reading and writing of a memory through a programmable logic device and is flexibly operated; the data read-write rate can be increased or decreased by changing a clock; furthermore, the single chip storage capacity of the memory is high and can be designed by a multi-chip storage mode, so that the storage capacity can meet a design requirement; multiple memory chips are operated at the same time, so that the read-write rate can be increased by multiple time of that of a single chip. Therefore, according to the mass data storage control module, high-speed real-time storage of mass data can be realized through the programmable logic device with high functionality and the large-capacity memory chips; the read-write rate of the data can be increased or decreased on the basis of a hardware platform by improving an operating strategy of the programmable logic device; moreover, by the adoption of the wide-temperature memory chips, the mass data storage control module can work in a severe environment to meet demands of different users.
Description
technical field [0001] The invention relates to the field of photoelectric product application technology, in particular to a massive data storage control module. Background technique [0002] With the wide application of microcomputers and the continuous improvement of various bus data acquisition products, many workplaces have established data acquisition and processing systems based on microcomputers. However, most of these devices work at low speed and normal temperature, and are suitable for continuous acquisition and processing of low-speed signals. For some high-speed data acquisition systems, most of them currently collect limited data. The reason for this is mainly due to the lack of Limitations of high-speed, high-capacity external memory devices. [0003] In recent years, the microcomputer technology has developed extremely rapidly, the computing speed has been continuously improved, and the memory and external capacity have been continuously increased. Whether t...
