Abstract

The invention discloses a CPCI Giga Bit Ethernet board card with strong real-time performance and a data communication method. The CPCI Giga Bit Ethernetboard card comprises a PCI bus controller, a programmable system-on-chip, a photoelectric conversion module and a high-speed memory, wherein the high-speed memory is connected with the programmable system-on-chip, and is used for storing process data in Ethernet real-time communication, and the programmable system-on-chip is a control center of the Ethernet board card. According to the invention, an ARM controller customizes a data protocol of Ethernet communication, so that fixed-period reliable transmission of data can be realized, and the problem of data transmission delay caused by an overtime retransmission mechanism of a traditional TCP / IP protocol is solved; and a direct data storage channel is established between a high-speed memory on the board card and Ethernet communication, so that the work of processing a large amount of data by the ARM processor is liberated, the data transmission efficiency is improved, and high-speed large-amount real-time data communication of the Ethernet can be realized.

Description

Technical field [0001] The invention belongs to the technical field of computer applications, specific to a strong CPCI Gigabit Ethernet board and data communication method.
