Abstract

The invention discloses a large-capacity high-speed multichannel data playback device and method. The playback device comprises a rack-mounted server, a D / A data interface board and at least two DDR data cache boards. The rack-mounted server is respectively in communication connection with the DDR data cache boards and the D / A data interface board, the DDR data cache boards are in communication connection with the D / A data interface board, and each DDR data cache board is in one-to-one correspondence with the output channel of the D / A data interface board. The device is flexible in configuration and can support multiple channel output modes. By configuring the D / A data interface board, various settings, such as internal and external clock selection, channel enabling control, channel output gain control, PPS synchronous enabling control, etc., can be realized; and by configuring the DDR data cache boards, the functional settings, such as data import, single play, loop play, start play, pause play, etc., can be realized, so that the large-capacity high-speed multi-channel data playback is realized.

Description

technical field [0001] The invention relates to the field of signal detection, in particular to a large-capacity high-speed multi-channel data playback device and method. Background technique [0002] As an important part of modern signal detection technology, data playback technology is the follow-up and derivative of data acquisition technology. It can be used as signal restoration and playback after signal collection for original signal analysis, and can also be used as an analog signal input source to generate various scene pulses (such as radar echo signals) for use in various occasions. [0003] With the rapid development of information technology, massive data storage and playback, multi-channel high-speed synchronous output application scenarios are becoming more and more important in many fields such as radar, communication, and remote sensing. [0004] At present, most analog signal data playback devices on the market are mainly realized by two schemes: one is PC ...
