摘　　要：在考察802.11b标准MAC协议的基础上,提出了MAC芯片设计的构架,并在设计中加入低功耗考虑因素,其中特别就作为控制模块的状态机的低功耗设计方法进行了尝试。通过仿真和验证,可以看到,在充分考虑低功耗因素后,系统的整体功耗将会下降,最核心的控制模块经过改进,功耗下降了近一半。Based on the power-focus analysis of the MAC protocol of 802. 11b standard, a system architecture for 802.11b MAC is presented and the low power concept is taken into consideration throughout the design. A low power structure for state machine operation as a control module is specifically proposed. By modifying the system with low power technology, a considerable drop on system power has been achieved, and simulation shows that the power consumption of the kernel control module has been reduced by 50 %.
