To get rid of the sometimes appearing endless loop at 87% of the wu I created new versions for Intel and PPC Mac and for 32- and 64 bit Linux. This problem happened for round about 10% of the work units on Mac and Linux.

为了避免时常在 87%附近反复循环的问题（约有10%在Mac和Linux平台的任务包会出现这种问题），我重写了 Intel 、 PPC Mac 上的32和64位 Linux 平台的计算程序。

Based on detailed working process of UWB-RI MAC, FI frame broadcast interval was analyzed and the support for QoS was explained. Finally, the performance simulation and comparison of UWB-RT MAC and UWB MACAW MAC were given.

通过给出的UWB-RI MAC协议数据收发的详细流程，分析了FI帧广播间隔的取值，说明其对QoS的支持；最后仿真比较了UWB-RI MAC和UWB-RI MAC和UWB MACAW MAC的性能。

For the partial products generation, the novel method of Booth encoding combined with partial products generating is put up, which can directly map the multiplicand and multiplicator to partition products without generating the BOOTH encoding results. For the optimization of Wallace tree adding, the series formulas of full-adder and 4-2 Compressor realization are introduced to guidance the selection. For the non-bias round, forwarding round disposal in Wallace tree method is brought forward to avoid the final multi-bit adder. Also, the idea of delay-oriented partition of the MAC frame is put up to achieve the perfect match with multi-pipeline DSP architecture.

提出了一种构建多模式算法最小并集的MAC通用结构思想与一种划分MAC通用结构以适应多流水级DSP处理器设计的通用MAC设计方法；对于BOOTH编码和部分积产生，提出了直接建立被乘数与部分积的多路选择映射关系的BOOTH编码和部分积联合产生方法；对于最优Wallace树型加法实现，提出了全加器和4-2 compressor电路实现Wallace树加法所需的关键加法路径级数公式以指导实现选择；对于无偏舍入处理，提出了在Wallace树处理舍入问题的舍入运算前置方法；提出了以时延为导向的MAC各部分单元组合与流水线匹配具体方法。

Methods 200 patients attending for colonoscopy were randomly chosen and divided into control group(n=100)and mac group(n=100).control group was given normal colonoscopy.mac group was given fentanyl (1μg /kg) and propofol (1～2 mg/s) intravenously.if the patients reached classⅴ of ramsay score,inserted the colonoscope,and maintained with propofol 5～10 mg/min.

200例行肠镜检查者随机分为mac组(n=100)和对照组(n=100)，对照组行常规肠镜检查。mac组以芬太尼1 μg/kg静脉注射，继以异丙酚1～2 mg/s速度推注，ramsay镇静分级5级后行肠镜检查，术中5 ～10 mg/min速度维持mac。

MAP and SVR in both groups changed unsignificantly changes at 0.5 MAC,while decreased obviously at 0.75 MAC and 1.0 MAC.No sigificant changes of HR,CVR and CI in two groups occurred at each MAC.

两组的MAP、SVR在0.5MAC时与基础值相比无显著变化，在0.75MAC及1.0MAC时相比基础值明显下降，而两组的HR、CVP、CI在不同MAC时与基础值相比均无显著变化。

First, the stations'timing process and the slot aligning are discussed. Second, the dissertation propose a resource request random access method based on feedback. The performances of this method are analyzed. Third, proceed from the considerations of the MAC protocol for the HFC system, a QOS-oriental scheduling algorithm for the MAC protocol based on dynamic TDMA is proposed. Simulation results show that the performance of this algorithm is better than that of the first come first service. Forth, two contention resolution algorithms ----p-persistent CRA and tree CRA, which are usually adopted in the HFC system, are summarized. The delay and characteristic are compared. At last, the dissertation introduces the function implementation of the MAC layer based on COM21 UPSTREAMS.

首先，讨论了基站的同步进程和时隙同步的实现；然后，本文提出了一种带反馈模块的资源申请信号随机接入方法，并对其进行性能分析；然后，从HFC系统的MAC协议出发，提出了一种用于基于动态TDMA技术的MAC协议的业务安排算法，计算机仿真结果表明其性能优于先到先服务法的性能；然后概述了常用于HFC系统的两种冲突解决算法——p-坚持冲突解决算法和树型冲突解决算法，比较两者的时延性能与特征；最后，介绍了基于COM21 UPSTREAMS协议的MAC层功能实现，给出了硬件框图和照片。
