Abstract

The invention provides a message processing method and device based on two groups of message processing engines. On one hand, in the embodiment of the invention, according to a message in a received write request sent by each entry message processing engine, at least one segment of each entry message processing engine is generated, and each segment comprises at most 2 messages in which the unit length is stored, so that each segment can be stored in 2 cache modules; each cache module is provided with a reading interface and a writing interface. As 4 cache modules, each of which is provided with a reading interface and a writing interface, are adopted to replace one cache module provided with 2 reading interfaces and 2 writing interfaces, a certain area can be saved technologically and the cost of exchange chips is lowered.

Description

technical field [0001] The invention relates to cache technology, in particular to a message processing method and device based on two sets of message processing engines. Background technique [0002] In a high-speed switching chip, one set of ingress packet processing engine and egress packet processing engine is far from being able to process high-bandwidth packets. Therefore, two sets of ingress packet processing engines and egress packet processing engines are required to simultaneously The message is processed to increase the processing bandwidth of the message. Shared cache is a commonly used structure in switch chips. In this switch structure, all input ports and output ports share a cache module, and all messages that need to pass through the switch chip are stored and forwarded in the cache. The advantage of this structure is that cache resources can be fully used, and the best performance of delay and throughput can be obtained. Therefore, the storage engine can ...
