Scheduling store-forwarding of back-to-back multi-channel packet fragments

Abstract

Disclosed is an apparatus and method for an interface for scheduling the store-forwarding of back-to-back multi-channel packet fragments. The apparatus may include a data extraction block, a plurality of data assemblers, a scheduler, and an output memory. The scheduler may be configured to operate according to a scheduling policy. The scheduling policy may include a set of priorities to determine an order of scheduling writes to the output memory from a plurality of data assemblers. The scheduling policy may also include selecting one or more of the plurality of data assemblers having a fill level greater than twice an input data path width of an input data bus and having no end-of-packet (EOP) or start-of-packet (SOP) as a first priority, selecting one or more of the plurality of data assemblers having a fill level greater than twice the input data path width of the input data bus, and not covered in the first priority selection, as a second priority, selecting one or more of the plurality of data assemblers having a fill level greater than the input data path width of the input data bus, and not covered in the first and second priority selections, as a third priority, and selecting one or more of the plurality of data assemblers having an end-of-packet (EOP) as a fourth priority.
