Abstract

The invention provides a data transmission method and system, and a chip. The data transmission method comprises the following steps: receiving an on-chip bus write access request; wherein the on-chip bus write access request comprises valid data; obtaining configuration information of a packaging head; packaging the effective data into a first Ethernet packet according to the configuration information of the packaging head, and sending the first Ethernet packet; wherein the first Ethernet packet comprises a packaging head and valid data.

Description

technical field [0001] The embodiments of the present application relate to the field of integrated circuit design, and in particular to a data transmission method, system, and chip. Background technique [0002] At present, the most widely used and most mature inter-chip data transfer (or inter-chip direct data access) is the high-speed serial computer expansion bus standard (PCIE, Peripheral Component Interconnect Express) interface, but the PCIE interface only supports point-to-point access, and the topology is different. Flexible, it can only support data transfer between chips on the board, and it is mainly used in X86 computer systems. In addition, the PCIE interface has a high operating frequency, complex interface implementation and debugging, and a single-channel bandwidth is limited. [0003] With the application of Ethernet technology more and more widely, the transmission bandwidth of Ethernet is getting higher and higher, and the Ethernet of chip interface is b...
