The invention discloses an enhancement-type large-capacity high-speed data exchange design method, and mainly relates to the technology of high-speed exchange transmission in the field of communication. A high-speed data transmission interface is implemented through the combination of a plurality of groups of high-speed serial transceivers Rocket I / O, wherein each group of high-speed serial transceivers Rocket I / O are corresponding to one exchange port, and completes the conversion between a high-speed serial data flow and low-speed parallel data. A circuit exchange network completes the exchange, copy and combination of high-speed data in a port and between ports through employing an enhancement-type T-shaped exchange structure, and can achieve dynamic adjustment of an exchange mode according to an external parameter configuration instruction. The method is large in exchange capacity, is strong in extensible capability, is dynamic and variable in exchange mode, supports the combination of data of multiple ports, supports a plurality of communication systems, and is suitable for the high-speed exchange and transmission of a large-capacity signal in a digital communication system.
Description
technical field [0001] The invention relates to a design method for enhanced large-capacity and high-speed data exchange in the field of communication, which is suitable for high-speed exchange and transmission of large-capacity signals in digital communication systems. Background technique [0002] In the digital communication system, it is necessary to exchange and transmit signals. As the amount of system data continues to rise, the requirements for exchange capacity are becoming more and more stringent. However, most of the current switching technologies have small switching capacity, fixed switching methods, limited supported communication systems, relatively fixed applications, and poor adaptability to some large-capacity communication or multi-system communication occasions. Contents of the invention [0003] The problem to be solved by the present invention is to provide an enhanced design method for large-capacity and high-speed data exchange by avoiding the short...
