摘要
针对无线传感器网络协议IEEE802.15.4安全模式的实现,基于GEZEL设计环境,选择较低成本的8bit微处理器平台Dalton8051,对安全模式配置和高级加密标准(AES)数据通路进行了软硬件协同设计与协同仿真.充分考虑处理器资源占用、系统灵活性,通信容许带宽,对设计进行了合理的软硬件划分、简单的指令设置,电路模块重用.实验结果表明该设计能够提供灵活的安全模式配置、最小化8051资源占用率、保证了协议868/915 MHz频段通信速率要求.
From the security suite of IEEE802.15.4, the hardware/software co-design was implemented and co-simulated under the design environment of GEZEL by an 8 bit low-cost microprocessor Dalton8051. In the design, the reasonable hardware/software partition, simple instruction setting and module reusing method were adopted to consider the resource occupation, system flexibility and acceptable band-width. The experimental results showed that the design could give more flexibility, less utilization of 8051, which could satisfy the data rate of the standard in the 868/915 MHz band.
