基于硬件多线程网络处理器功耗可控无线局域网MAC协议实现
Power controllable WLAN MAC protocol implementation based on hardware multi-threaded network processor
摘要
Abstract
How to improve network throughput and meet the real-time while consuming less power process are key concerns during network processor designing. Hardware multi-threaded network processor as a platform, IEEE 802. 11MAC layer proto-col as an example, modeling based on MAC layer data stream model, data stream operation behavior and time constraints and test the model. This paper presented a multi-threaded network protocol software implementation method. This method could adjust system performance based on traffic and real-time with dynamic power controlled multi-threaded network processor, thereby reducing power consumption when the processor was running. The result shows that real-time tasks require 4 hard threads on multi-threaded processor while only 2 are required for non-realtime tasks. This programming model provided proces-sors the ability to dynamically adapt network workload characteristics.关键词
