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 xl 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.
