Transporting data transmission units of different sizes using segments of fixed sizes

摘要

A data traffic management system that has the capability of writing data to the buffer memory at twice its normal rate. The data traffic management system uses a pointer structure that can reference either a single or a dual segment memory bank. A dual segment memory bank enhances the write capability of the data traffic management system by allowing two segments to be simultaneously written to both segment memory banks, with one segment being written to each bank. A pointer data structure with a single/dual indicator (S/D indicator) is used for referencing the memory banks. If the S/D indicator has a D entry, then a dual segment memory bank is addressed. The S/D indicator will have an S entry if a single segment memory bank is addressed. Based on the contents of the S/D indicator, either a single fixed size data segment is written to a single memory bank or two fixed size data segments are written to a dual segment memory bank.
