Development Solution for Multi-channel Signal Acquisition and Processing Module

Develop a multi-channel optoelectronic signal acquisition and processing module to implement acquisition, processing, and storage functions for 64 sensor channels. It mainly comprises data acquisition and processing circuits, system control software, signal processing algorithm implementation, and data storage. This includes 8-channel ADCs, where each ADC's sampled data corresponds to 8 sensor signals, totaling 64 sensor signals acquired. The processing chip performs real-time signal processing on each of the 64 sensor signals and stores them to a hard drive.

Signal Processing Flow: 8-channel AD acquisition (typical sampling rate 80MHz) -- Pre-processing to generate 64 raw signals with a typical sampling rate of several hundred kHz (typical value 400kHz) -- Real-time computational processing of 64 raw signals -- Storage to hard drive and transmission to external devices via network.
