Abstract

The invention provides a cross-board daisy chain transmission structure, a master board, slave boards and a system. The cross-board daisy chain transmission structure comprises a master board and N slave boards which are connected in series in a daisy chain mode, N is larger than or equal to 1, and N is an integer; the master board is directly connected with the slave boards, and a clock line and a data line between the slave boards are directly connected; and the master board and the slave boards as well as address lines between the slave boards are connected in a preset staggered manner. Compared with the prior art, the cross-board daisy chain transmission structure, the master board, the slave boards and the system have the advantages that the number of connectors and drivers of the master board is reduced, the number of materials for connecting the master board and signal lines of the slave boards can be remarkably reduced, and the cross-board daisy chain transmission structure has good expandability.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a cross-board daisy chain transmission structure, a master board, a slave board and a system. Background technique [0002] With the continuous advancement of technology, the functions of computers tend to be diversified, and various peripheral devices are constantly being introduced. In order to facilitate users to improve computer performance or expand computer functions, accelerated graphics are generally configured on the motherboard of the computer. Accelerated Graphics Port (AGP), Peripheral Component Interconnection (PCI), Express PCI (PCI Express, PCI-E) and other bus slots for users to insert graphics cards, sound cards, network cards and other expansion cards. In addition, expansion interfaces such as Firewire, Universal Serial Bus (USB), IIC bus and / or SPI bus will also be configured on the host computer for users to connect external devices such as hard disk...
