Summary:The invention belongs to the field of micro electronic technology and particularly relates to a "butterfly" transmission method for an assembly line between cascaded boards. According to the method, regular communication between a host and a PCIe bus between board cards serves as a complete assembly line working mode at an independent flow level, all user logic distributed on all the board cards can work ceaselessly in a compact assembly line mode, and the viscidity of calculation is remarkably enhanced; the total system throughput rate only depends on calculation consumed time of the user logic and is not influenced by increase of the quantity of the cascaded board cards; an access method of a "butterfly" structure is further proposed according to data transmission under the complete assembly line working mode; and by separating reading/writing data channels, the bandwidth of an onboard double-DDR controller is fully utilized, and transmission performance is nearly doubled compared with a single-DDR controll
