Interrupt generator with synchronization function
This application relates to an interrupt generation device with synchronization function. By using one of the interrupt generation modules as a reference interrupt module, when the synchronization signal output by the synchronization output module arrives, the reference timing module adjusts the count of each interrupt module according to the synchronization signal, the reference count of the reference interrupt module, and the timing duration of the reference timing module itself, so as to change the output time of each subsequent interrupt signal. This makes the output reference interrupt signal synchronized with the synchronization signal, and other interrupt signals still maintain the initial phase relationship with the reference interrupt signal before adjustment, and eventually synchronize with the synchronization signal. In this way, only one synchronization signal is needed to ensure that the synchronization of all interrupt signals is achieved without changing the phase relationship between the interrupt signals of each interrupt generation module. The method is simple and has high synchronization accuracy.
