Abstract

The invention discloses a system and a method for UDP high speed data transceiving. The system comprises an MAC layer, a UDP/IP protocol stack, a cache control module, a CI module and a soft core processor which are integrated in an FPGA, wherein the MAC layer is used for analyzing received data of an external physical layer, sending the data to the UDP/IP protocol stack, packing data from the UDP/IP protocol stack and sending the packed data to the external physical layer, the UDP/IP protocol stack is used for analyzing received effective data of the MAC layer, sending the data to an application layer through the soft core processor, packing data from the application layer and sending the packed data to the MAC layer, the cache control module is used for controlling reading and writing of the external cache, and the CI module is used for controlling data interaction between the soft core processor and the UDP/IP protocol stack and between the soft core processor and the cache control module. According to the system, hardware logic processing is employed respectively for the protocol stack and cache control, the soft core processor is only for parameter configuration, the soft core processor is prevented from excessively interfering data transmission and storage, system bandwidth is greatly improved, and high speed data transceiving can be realized.

Description

technical field [0001] The invention belongs to the technical field of Ethernet, and more specifically relates to a UDP (User Datagram Protocol) high-speed data transceiving system and method. Background technique [0002] At present, the Ethernet functions based on soft-core processors are generally realized by using software protocol stacks. Due to the low performance of soft-core processors, the way of using software protocol stacks cannot give full play to the high bandwidth performance of the network. With 1000MBase-T Take the network as an example, the actual bandwidth can reach 1Gbps, but in the application environment of the software protocol stack based on the soft-core processor, the actual bandwidth can only reach a few Mbps, which greatly limits the bandwidth of the network, making the architecture based on the soft-core processor The application development of network equipment is greatly restricted. [0003] With the continuous development of video technology,...
