Data Parallel Transmission Algorithm of Multi-channel Sampling Based on Serial controller

In order to enhance the transmission efficiency of the multi-channel seismic data parallel sampling using serial controller,under the inspiration of pipelining and rotation time slice,a transmission control algorithm was proposed using a group of SPI to realize parallel high-speed data acquisition and parallel transmission of multi-channel ADC.Using time overlap parallel processing,this method can make the sum of transmission time of single synchronous sampling data of multi-channel ADC slightly more than that of single channel ADC.Therefore,the transmission efficiency between the central controller and the multi-channel ADC has been improved.
