Abstract

The invention discloses a high-speed data transmission system and method based on PCIE. The high-speed data transmission system comprises a host, an FPGA module and a PCIE bus, the PCIE bus is used for connecting fast communication between the host and the FPGA module, the host and the FPGA module are both provided with a PCIE interface in insertion connection with the PCIE bus, the host is a mainend of the PCIE bus, the FPGA module is a secondary end of the PCIE bus and used for completing read-write operation on DMA. The high-speed data transmission system and method based on the PCIE havethe advantages that the DMA, address mapping, interruption and the like are mainly controlled between the host and the FPGA module, the speed of the data transmission is improved, the reliability of the data transmission is ensured, the high-speed data transmission system and method can be applied to some equipment for high-speed data interaction with the host, such as data acquisition cards, FPGAacceleration cards and the like.

Description

technical field [0001] The present invention relates to a data processing system and method, and belongs to the field of computer technology, in particular to a PCIE-based high-speed data transmission system and method. Background technique [0002] With the continuous development of computer technology and information technology, the speed of some existing data transmission systems can no longer meet the requirements of communication systems and data acquisition systems for data transmission speed. [0003] As a new generation of data transmission bus, PCIE bus adopts end-to-end and differential serial mode for data transmission. This transmission mode has better advantages in terms of power consumption, speed, and reliability. [0004] Between the host and various data modules and FPGA modules, high-speed and accurate data transmission is often required to meet the requirements of data exchange and processing, but traditional data transmission systems in the prior art ofte...
