无线传感器网络MAC层通信芯片设计

Design of wireless sensor network MAC layer communication chip

提出了应用在无线传感器网络系统的MAC层通信芯片的ASIC设计方案,基于IEEE802.15.4竞争型MAC协议,设计了内嵌CSMA-CA算法控制器的MAC收发模块以及8位RISC CPU,MAC收发模块的协处理器可以与RISC CPU进行数据交互。基于ASIC设计流程,完成了架构设计、RTL coding、验证、综合、物理设计,并通过Encounter生成了物理版图。

This paper puts forward a ASIC design scheme of MAC layer communication chip, designs a MAC chip including a CSMA-CA algorithm controller embedded in a MAC transceiver chip module based on the competitive IEEE 802.15.4 MAC proto- col and a 8 bit RISC CPU, on which the MAC transceiver chip module can exchange date with the RISC CPU. Based on the A- SIC flow, this paper completes the chip design of architecture, RTL coding, verification, synthesis and physical design, and also generate the final chip layout by Encounter software.
