Abstract

The invention is applicable to the technical field of electronics, and provides a programmable delay trigger pulse synchronization device, which comprises a pulse input unit, a programmable logic array, a pulse output unit and a control unit, wherein the pulse input unit is used for inputting multiple paths of pulse signals to the programmable logic array; the programmable logic array is formed bymultiple paths of delay channels, and the multiple paths of delay channels are respectively used for carrying out delayed time processing on the multiple paths of pulse signals in order to output multiple paths of synchronous signals to the pulse output unit; the control unit is used for configuring the number of the delay channels in the programmable logic array and the delay time of each delaychannel; and the pulse output unit is used for outputting the multiple paths of synchronous signals to a lower-level circuit. According to the device, the number of the delay channels and the delay time of each delay channel can be conveniently and flexibly changed, a circuit hardware structure of a synchronous machine is simplified, and the hardware cost of synchronous machine products is reduced.

Description

technical field [0001] The invention belongs to the field of electronic technology, in particular to a programmable delay trigger pulse synchronization device. Background technique [0002] In complex large-scale physical implementations or complex instrument systems, there are generally multiple instruments of different types or different individuals of the same type of instruments that need to coordinate their work. The station is delayed for a period of time to work, so it is necessary to trigger the synchronous machine to give synchronous signals respectively, so that these numerous instruments can be coordinated to form an instrument system. [0003] see figure 1 As shown, the existing trigger pulse synchronization technology is realized by combining a 1:N fan-out chip with a discrete delay-adjustable chip, where N is a positive integer, and multi-level cascading of 1:N fan-out is used to realize the expansion of multi-channel signals . This kind of trigger pulse syn...
