ABSTRACT:
The inventive mechanism is included with each module in a chain of modules. The inventive mechanism includes a clock mechanism which is edge synchronous among all of the clock mechanisms in the other modules, meaning that each clock has the same frequency and zero phase delay with respect to the clocks of the other modules. The clock mechanism of the first module of the chain is the master, the subsequent clocks are slaves. The inventive mechanism includes a trigger mechanism which allows each module of the chain to initiate a trigger event. The trigger mechanism is tied to the clock mechanism, so that the trigger signal is sent out on the next rising edge of the clock. Since each module is tied to the same clock frequency and has zero delay, when one module sends out a trigger, the remaining modules will detect the trigger on the next clock cycle, and the trigger event will begin simultaneously in all modules.
