A rapid burst signal acquisition module based on multi-chip collaborative processing

This invention proposes a rapid burst signal acquisition module based on multi-chip collaborative processing, belonging to the field of signal processing. The module includes a clock synchronization chip, a main computing chip, and N-1 auxiliary computing chips. The clock synchronization chip generates a 1PPS pulse signal and a system reference clock. The main computing chip receives externally input sampled data and distributes it evenly among the N computing chips. Each computing chip performs its own acquisition calculation on the received data to obtain the acquisition result. The auxiliary computing chips return the acquisition result to the main computing chip, which then comprehensively evaluates all acquisition results and outputs the final acquisition result. By constructing a "1 master + N slave" distributed computing architecture and employing a three-level collaborative mechanism of time synchronization, phase slicing, and result fusion, the module effectively solves the problem of weak signal acquisition for consumer terminals in the BeiDou short message system.
