Research on Parallel Multi-Channel Ultrasonic Data Cache and Transfer Method Based on RIFFA Framework PCIe Bus

In order to meet the needs of high-speed cache and transfer of parallel multi-channel ultrasonic system, this paper proposes a segmented cache method suitable for ultrasonic data organization and transfer, and completes the design of PCIe parallel multi-channel ultrasonic data interface based on RIFFA framework. The experiment verifies the reliability of the segmented cache method, realizes the cache and transfer of parallel 8-channel ultrasonic data, and the PCIe Gen2 x1 bus based on RIFFA 2.2.2 framework has a transfer rate of 395 MB/s. The research content of this paper is highly scalable and portable, and can be applied to a variety of multi-channel ultrasonic testing systems.
