d channel meaning in English
三维通道
Examples
- Link access protocol for d channel lapd
通道链路接入协议 - According to the characteristics of the signal under testing , the user can configure the sampling rate and range . besides , different a / d channels can work under different sampling rates and ranges
用户可根据被测信号特征,通过程序设置采样频率、量程,可实现各a / d通道在不同采样频率和测量范围下工作。 - It contains two a / d channels , every channel has a 4kx 16bit buffer . it has three flexible trigger modes : inner trig , outer trig and software trig . vvp platform can support up to 4 plug - in boards ( 8 channel a / d ) to work together
该模块作为一块vvp仪器平台上的插板，采用20msps的16位a d转换器，一块插板上设计了2个高速a d转换通道，每个通道有4k 16位的缓冲存储器，可以内部触发、外部触发和软件触发。 - And software method can resolve d channel ' s work for its less data communication ; 3 ) cpu 80c152 is synchronized with mc145572 by a simple synchronous circuit , avoiding the complex fpga interface circuit ; 4 ) data transmission use dma , which reduces the delay of data transmission and cpu occupying ; 5 ) 8bit software look - up table method can achieve 16bit crc quickly , which reduces the resource of both hardware and software
对通信数据量相对小的d信道，采用软件实现装帧与解帧。第三，采用结构简单的外部同步时钟电路实现80c152和接入芯片mc145572的同步传输，巧妙地避开了复杂的fpga接口电路。第四，利用dma技术完成数据快速收发，降低了数据传输时延及cpu占用率。
