【摘要】 超大规模集成电路工艺技术迅猛发展,集成电路已能在单芯片上集成整个系统,从而使VLSI进入SOC设计阶段。SOC系统集成技术具有易于增减功能单元和缩短产品设计开发时间等的显著特点,是集成电路设计界当前、乃至可预见未来的主流设计方法。IP核的设计与复用是SOC技术的基础和关键。SOC系统集成技术和IP设计技术越来越成为集成电路业界广泛关注的焦点。同样,作为一种全球统一的无线连接标准的蓝牙技术,从规范的推出到现在的两年多时间里,各国所投入的人力、物力以及研究人员所投入的热情是罕见的。蓝牙技术及产品以其方便、可靠、易于使用而且廉价等特点,被誉为新经济的引擎,是当今世界研究和投资的热点。本文以这两大研究热点为基础,深入研究了现代SOC系统集成设计方法、系统划分设计理论、IP设计方法等等,并对蓝牙基带技术的关键部分进行了仔细分析,在EDA仿真系统上实现了其IP。获得一些有价值的结果和新颖的方法。主要内容如下: 1.提出了一种新的SOC系统集成设计方法与流程;总结了IP设计所应遵循的设计标准和参考流程;给出了应用于SOC系统集成设计中的仿真模块生成技术与方法。 2.应用拓扑图论的分割理论进行了系统划分模型的研究,并对其作了适应SOC分割的改进;给出系统划分的代价函数和约束条件;给出了改进遗传算法的实现结构,并指出了通用的蓝牙系统软硬件划分和基带实现结构;给出了新的蓝牙基带的数据处理路径结构,采用串行方式实现可优化硬件资源。 3.独立设计并实现了蓝牙基带的跳频选择系统算法软IP;EDA仿真表明该算法能很好地满足设计目标与要求。 4.对蓝牙安全体系的各种算法进行了综合研究;独立设计和实现了蓝牙基带安全系统;根据流控设计思想对算法的核心功能函数A_r的推荐流水线实现方法进行了改进,得出一个全新的流控设计实现方案。比较两种实现方案,理论上芯片面积、功耗、运行效率等有近75%的改进;实际的仿真、综合结果 电子科技大学博士论文一与之相一致。 5.为了实现上的方便,提出了蓝牙时钟实现的几种模式的新定义;给出识别码的同步字生成过程在工程实现上的数学模型;设计了蓝牙系统时钟的软IP、识别码发主器的软*以及它们功能仿真。 6.在工程上,采用CPU预置和读写控制字的思想,设计并实现了识别码相关器、分组可靠传输的方法(FEC、CRC和数据加噪等)以及收发数据分组的缓7中与控制等的软*。
【Abstract】 The manufacturing technology of VLSI has being developed rapidly, and a whole system can have been integrated in a chip, the VLSI comes into SOC design stage consequently. The SOC technology has some obvious characteristics: adding and deleting function unit easily; shortening production design and exploiture period. It must be future main design method in 1C design world presently and later. The design and reuse of the IP core are the foundation and key of the SOC technology. The SOC and IP are becoming the attention focus in 1C world more and more. On the other hand, Bluetooth is a unification specification of wireless connection in the seven seas, in two/threee years, many country invest much more manpower and material resources, and the researcher’s passion is rarely high, too. Bluetooth is praised " New Economy Engine" because of the facility and credibility in usage, cheapness and etc., it is the hotspot of researching and investing in the world. In this paper, on the basis of the two aspects, SOC methodology, system partition theory and IP methodology are studied, Some key parts in Bluetooth Baseband are studied carefully and their IP are designed in EDA simulation system. Some import results and new methods are presented. Following is the detail:1. A new scheme and the flow-process are given about the SOC design. The criterion and reference flow-process are pointed out about IP design. The technology and method on generating simulation module are given and they can be used in SOC design.2. The partition theory of graphics is applied in studying on system partition theory and it is improved on to fit SOC system paration. The wage function and restriction conditions in the system partition are given. The realizing structure of the modified Gas algorithm is given, and the general partition about softwareIII -and hardware of the Bluetooth system and the BB structure design are described. The new data process path in Baseband is constructed to optimize hardware resource when it is realized by the means of serial bit processing.3. Software IP of hop selection algorithm in Basband is designed and realized independently. EDA simulation indicates the hop algorithm can meet the design aims and needs primely.4. All algorithm of Baseband security are studied synthetically. The Bluetooth Baseband security system is designed and realized independently. And according to the idea of flow control, the implementing method of the kernel function Ar in these algorithms is offered, which is different from the recommend pipeline method, and a new scheme is obstained. The two implementing method are compared, theoretically the chip area, power dissipation and efficiency are improved 75% on. The conclusion is proved by results of EDA simulation and synthesis.5. To realize easily, the new operating modes definitions for the clock in Bluetooth are given and mathematic model of the sync_word building on engineering is given. The software IPs about the clock and the access code generating are designed. And their functional simulations are realized.6. Adopting the idea of control registers which are preset and read-writted by CPU, some software IPs are designed and implemented which contain access code correlator, credible packet transfers algorithms (FEC, CRC and Whiten) and the data packet Tx/Rx buffers.
