The development of big data has generated huge amounts of data, and the dataset often contains duplicate data. It is difficult to meet the requirements of big data and high bandwidth with traditional CPU-based algorithms that use hash tables for processing. Data storage acceleration can be achieved through pre-processing to identify duplicated data in FPGAs.The Pango Micro Titan-2 FPGA products achieve PCIe 3.0x8, 1866Mbps DDR4@64bit, hash hardware acceleration algorithms, multi-level indexed storage, error classification and other major functions in its acceleration card solutions.
