serial interface engine造句

• The main chip of the usb interface circuit is a cypress semiconductor ' s product , cy7c64613 , which has intergrated usb sie ( serial interface engine ) and enhanced 8051 . the oscilloscope module is realized according to the real time sampling principle . it has two signal chunnels and a dual 8 - bit dual a / d converter whose most sampling rate is 40msps , so two signal acquisition can occurs in the same time
  随后介绍虚拟仪器测试平台中各硬件模块设计实现： usb接口的主芯片是cypress公司的cy7c64613 ，此芯片集成了usbsie和8051核；示波器模块根据实时取样原理实现，采用双8位a / d转换器，提供两条信号通道，可以同时采集双路信号，最高的采样率为40mhz ；信号源模块采用直接数字合成( dds )原理实现，它所能产生的信号频率为10hz 5mhz ，最小频率分辨率为9 . 537hz 。
