Abstract
A method for processing data packets in a pipeline and executed by a network processor. The pipeline includes a plurality of logical blocks, each logical block configured to process one stage of the pipeline. Each data packet includes a descriptor and a data. The network processor is coupled to a resource for storing the data. The method reduces latency and enables non-blocking processing of data packets by forwarding a unique identification of a write request from a first logical block to a subsequent second logical block in the pipeline, the write request to modify the data in the resource. The method includes receiving the descriptor for processing at the first logical block, generating the write request and the unique identification for the write request, transmitting the write request to the resource, and transmitting the unique identification towards the second logical block before an acknowledgement is returned by the resource.
