Embodiment Construction
[0032] The specific embodiments of the present invention will be described below with reference to the accompanying drawings.
[0033] like figure 1 As shown, the real-time and reliable waveform data transmission circuit between the FPGA and the microcontroller in this embodiment includes: a conflict detection module, a waveform data candidate storage module, a data cross-clock domain module, a waveform data acquisition module, and a microcontroller interface module .
[0034] The analog-to-digital conversion module is arranged at the front end of the waveform data acquisition module. The waveform data acquisition module is configured to send a conversion start signal to the analog-to-digital conversion module at its front end, so that the analog-to-digital conversion module performs analog-to-digital conversion on the target signal based on the start conversion signal, and the waveform data acquisition module is based on the start conversion signal. The conversion signal pe...
