Exchange circuit based on exchange channel

Abstract

The invention provides an exchange circuit based on an exchange channel. The exchange circuit comprises an exchange scheduling module, a storage management module, an input control module, an output control module, an input and output intercross switch, an exchange channel module and a storage control module. The exchange channel is used as a control center, the data exchange with input ports and output ports is realized through the input and output intercross switch, the exchange scheduling module completes arbitration, allocation and recovery of exchange channel units, the exchange channel module responds to the output ports with the same storage data requests for many times, the fast access of data is realized, the connection with a high-capacity external memory is realized through the storage control module, and the storage requirement of high-capacity data buffering is realized. The exchange circuit has the advantages that the designs of storage forwarding, intercross switching, high-speed buffering and the like are combined, and the exchange bandwidth, the exchange delay and the expandability are superior to those in the prior art.

Description

technical field [0001] The invention belongs to computer hardware technology and relates to a switching circuit based on switching channels. Background technique [0002] The communication and expansion of computer networks require switches to exchange data. Switching circuits generally include shared bus switching, shared storage switching, fully interconnected switching, and crossbar switching. Shared media switching circuits such as shared buses and shared storage are relatively inefficient. Both the switch and the crossbar switch need to occupy a relatively large internal memory, and the memory capacity limits the aggregation bandwidth of the switch. Contents of the invention [0003] The purpose of the present invention is to provide a switching circuit design circuit based on switching channels, which can expand multiple switching channels according to actual applications, realize parallel switching between multiple input and output ports, and effectively solve switc...
