Abstract

The invention discloses a multi-core and multi-threading processor-based functional macropipeline implementing method. A plurality of processors are divided into different clusters, namely a receiving cluster and a transmitting cluster; the plurality of processors have parallel structures in the receiving cluster and the transmitting cluster; the receiving cluster is responsible for receiving messages, a parallel structure is adopted in the receiving cluster, and all packet receiving tasks are completed parallelly by a plurality of threadings; and the transmitting cluster is responsible for transmitting the messages, including checking whether a new data packet transmitting task is present, acquiring queue descriptor information of the current head pointer after reading a new transmitting task, transmitting a data packet from a synchronous dynamic random access memory (SDRAM) unit specified by a descriptor to a specified transmitting buffer unit and maintaining synchronous communication between the head pointer of a queue and the receiving cluster, a parallel structure is adopted in the transmitting cluster, and all packet transmitting tasks are completed parallelly by a plurality of threadings.

Description

technical field [0001] The invention relates to a method for realizing a function macro pipeline based on a multi-core multi-thread processor. Background technique [0002] With the rapid growth of network bandwidth, the programmability and versatility requirements of various network entities such as routers, switches, and gateways continue to increase. It is necessary to develop more complete applications to better utilize the performance advantages of multi-core processors. To meet the needs of various high-throughput, low-latency multimedia network communications has become the main problem currently facing. However, under the current parallel processing structure of various multi-core network processors, because the flexibility and high efficiency of parallel programming have not been well demonstrated, the parallel network processing capability is limited. The network parallel processing capability needs to take into account the hardware parallel structure and the para...
