System and method for realizing multichannel data two-way transmission

Abstract

The invention discloses a system for realizing multichannel data two-way transmission. The system comprises a data interface module, a multichannel transmission module, a data cache management module and a PCIe transmission module which are sequentially connected according to a data transmission direction, the data interface module receives data of external terminal equipment and transmits the data to the multi-channel transmission module; the multi-channel transmission module collects data of a data interface, transmits the data through a plurality of transmission channels, arbitrates according to priorities of the plurality of transmission channels, and outputs the data to the data caching module; transmitting the data to a data interface according to the channel identifier; the data caching module receives and caches the data, manages a caching space according to the channel identifier, and transmits the data to the multi-channel transmission module; the PCIe transmission module transmits the data to the PC, receives the data transmitted by the PC and transmits the data to the data caching module. Through a multi-channel data transmission structure and management of a cache address, data transmission has extremely high expandability.
