Title:
FPGA-BASED SQUARE-WAVE GENERATOR AND SQUARE-WAVE GENERATION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/124219
Kind Code:
A1
Abstract:
An FPGA-based square-wave generator and a square-wave generation method. The generator comprises a bus control module for receiving a broadcast command and a broadcast address sent by an upper computer; a waveform broadcast management module for receiving the broadcast command and the broadcast address, reading original waveform data from a storage module according to the broadcast command and the broadcast address, decoding the original waveform data to obtain waveform data, generating delay data according to the waveform data, and outputting the waveform data and the delay data; a parallel-serial conversion unit for receiving waveform data input in parallel and serially outputting the waveform data to obtain a square-wave signal; a delay chain unit for delaying the square-wave signal; and a multi-path selection controller for receiving the delay data, determining an output node, for the square-wave signal, on the delay chain unit according to the delay data, and leading out a corresponding delayed square-wave signal from the output node and outputting the signal. By means of the present invention, square-wave signals with high accuracy and no dead time can be continuously output.
