摘要
针对在远距离高速传输中数据可靠性比较低的问题,提出了一种带半字节CRC直驱表法校验的高速长线HOTLINK数据传输系统设计。设计以HOTLINK作为高速数据传输接口,将反馈纠错机制(ARQ)运用在传输系统中,并在逻辑设计上加入半字节CRC检错码,提高数据传输的可靠性,保证数据高速传输。经验证,数据能以400 Mbit/s的速率,在由4段20 m射频同轴电缆组成的80m传输线上可实现零误码率传输。有效保证远距离高速传输中数据的可靠性。
Aiming at the problem of low data reliability in long-distance high-speed transmission,a high-speed long-line HOTLINK data transmission system with half-byte CRC direct drive table method verification is proposed.Designed with HOTLINK as the high-speed data transmission interface,the feedback error correction mechanism(ARQ)is applied to the transmission system,and a nibble CRC error detection code is added to the logic design to improve the reliability of data transmission and ensure high-speed data transmission.It has been verified that the data can be transmitted at a rate of 400 Mbit/s on a 80 m transmission line composed of 4 sections of 20 m RF coaxial cable.Effectively these guarantee the reliability of data in long-distance high-speed transmission.
