WORK REQUEST PROCESSOR

摘要

A network processor includes a schedule, sync and order (SSO) module for scheduling and assigning work to multiple processors. The SSO includes an on-deck unit (ODU) that provides a table having several entries, each entry storing a respective work queue entry, and a number of lists. Each of the lists may be associated with a respective processor configured to execute the work, and includes pointers to entries in the table. A pointer is added to the list based on an indication of whether the associated processor accepts the WQE corresponding to the pointer.

主权项

1. A scheduling processor for scheduling work for a plurality of processors, the scheduling processor comprising:
an add work engine (AWE) configured to forward a work queue entry (WQE) to one of a plurality of input queues (IQs); an on-deck unit (ODU) comprising a table having a plurality of entries, each entry storing a respective WQE; and a plurality of lists, each of the lists being associated with a respective processor configured to execute WQEs and comprising a plurality of pointers to entries in the table, each of the lists adding a pointer based on an indication of whether the associated processor accepts the WQE corresponding to the pointer; and a get work engine (GWE) configured to move WQEs from the plurality of IQs to the table of the ODU.
