Abstract

This work presents some new optimization approaches to implementation of medium access control (MAC) layer of IEEE 802.11 wireless networking protocol using general purpose DSP and gate array systems. Optimization starts at design level. The hardware/software partitioning of the MAC's architecture is optimized in the sense of minimal implementation burden, while maintaining the system's functionalities and performance. The proposed partitioning and implementation technique obviates the use of any real time operating system (RTOS), which leads to a simple, high speed, and low memory structure of the MAC's software. Also, solutions such as using hash tables and pipeline processing are given and employed to gain a higher speed. The software section is implemented on the popular, low price DSP of TI's C54 processor, whereas the hardware implementation is realized using Virtex2vp30 from Xilinx
IEEE802.11介质访问控制的一种新实现
本文提出了利用通用DSP和门阵列系统实现IEEE 802.11无线网络协议的介质访问控制(MAC)层的一些新的优化方法。优化从设计层面开始。MAC架构的硬件/软件分区在实现负担最小的意义上进行了优化,同时保持了系统的功能和性能。所提出的分区和实现技术避免了任何实时操作系统(RTOS)的使用,这导致了MAC软件的简单,高速和低内存结构。此外,还提供了一些解决方案,如使用哈希表和管道处理,以获得更高的速度。软件部分在TI公司的C54处理器上实现,而硬件部分使用Xilinx公司的Virtex2vp30实现
