In the field of image and radar signal processing, a system is usually required to work together with multi signal processing board. In order to realize the high-speed data transmission and communication between the various circuit boards, a new high-speed data acquisition and testing platform is designed.The platform uses 64B/66B encoding, and is compatible with 8B/10B encoding, uses optical fiber as the transmission medium, uses high performance FPGA to achieve high-speed data transceiver. The result of test provides that the platform using of the 64B/66B encoding compared to the platform using of the 8B/10B encoding greatly improves transmission efficiency and significantly reduces data redundancy at the same time. This platform has a strong universality and improves the speed of communication. It also can simplify the complexity of the peripheral circuit. Therefore, the platform can be used to provide a more efficient hardware support for ultra high speed data acquisition,and have strong practicability.
