Abstract：A scheme of the parallel ADC system for ultra-high speed precision is introduced in the paper. The design of hardware system is proposed and the composition is described in detail. software function modules and Algorithms for Signal Processing is briefly introduced and The sampling datas for four signal are tested though embedded logic analyzer and testing errors are analyzed. The sampling rate for 1GHz and 12bit resolution can be realized in the parallel ADC system for ultra-high speed precision. The follow signal processing platform has some universality and application value in project.
