Methods and apparatus related to a shared memory buffer for variable-sized cells

摘要

In one embodiment, an apparatus includes a shared memory buffer including a lead memory bank and a write multiplexing module configured to send a leading segment from a set of segments to the lead memory bank. The set of segments includes bit values from a set of variable-sized cells. The write multiplexing module further configured to send each segment from the set of segments identified as a trailing segment to a portion of the shared memory mutually exclusive from the lead memory bank.

主权项

1. A method, comprising:
receiving at an input register a cell of an input signal, the input signal including a plurality of cells that includes the cell, the cell including a plurality of segments; determining whether a memory bank from a set of memory banks is a write destination of a segment from the plurality of segments when the segment is a leading segment of the cell, the set of memory banks defining at least a portion of a cut-through buffer; and modifying a flow rate of the segment through the memory bank in response to a flow control signal received at the input register.
