A High Performance Buffer Management Mechanism for Embedded Stack
This paper proposes a two stage buffer management mechanism MYBUF,it has memory protected mode,configurable,support static and dynamic allocation and backup allocation,this mechanism which has high performance,simple and reliable characteristic meet the management requirement of embedded system.By using this MYBUF Buffer Management Mechanism,data zero copy technology has been realized while transfer data through the embedded TCP/IP stack.The management mechanism has been successfully applied to the bidirectional system platform for HDTV(High Definition Television),which has DOCSIS MAC layer chip developed in our lab,and meets the demands of set top box and other embedded system network communications.The tests in real network conditions show that the system provides a good performance and reliability.With generality,the MYBUF buffer management mechanism can be applied to other embedded network communication system.
