Connect an external network co-processor to a network processor packet parser

摘要

Optimizing the number of lanes of a network processor when translating request / response traffic between the parser of network processor ethernet ports and an external coprocessor indicates, upon receipt of a 64-byte Ethernet packet in the Ethernet port and during In the parsing period, the parser sends a 16-byte word request to the coprocessor on the other (bidirectional) 3,125 lane, and in response receives a 16-byte word on the other (bidirectional) 3,125 lane. 16 byte byte co-processor access traffic and one unit (bidirectional) traffic in the network processor can be statically multiplexed, with one or the other traffic being established when the network processor is initialized. A 16-byte word processor coprocessor access traffic is multiplexed dynamically in one Ethernet port and 16-byte coprocessor access traffic in another Ethernet port, where dynamic multiplexing is arbitrated with a wrap-around algorithm.
