A New Type of Seismic Recorder by GPU/CPU Vibroseis Data Correlation Processing Technique

摘要

As an advanced parallel computing technique,GPU (graphics processing unit) parallel computing can be introduced into the vibroseis data correlation processing.Based on this,we design a new type of digital seismic recorder which implements the vibrator data correlation using GPU/CPU co-processing technology.The procedure of field data reception and presentation,data storage and organization,process control,progress control and display are conducted by CPU,while the process of high-speed correlation is conducted by GPU with a parallel algorithm.Then this kind of seismic recorder can efficiently complete massive vibrator data correlation processing operations.The introduction of the GPU/CPU co-processing technology makes the digital seismic recorder systems have many advantages over traditional DSP technology on vibrator correlation process,such as simpler structure,cost reduction,more reliability,etc.It can also increase the system upgrade ability.
