ABSTRACT0541363Joseph R. CavaliaroWilliam Marsh Rice UniversityUnifying Application Specific Processors for Communication SystemsA new generation of mobile wireless devices that are always connected through a multitude of standards for different indoor and outdoor environments is emerging. This project seeks to unify these various algorithms and architectures through identifying commonalities in representation and translation. As wireless data rates exceed 100 Mbps and approach 1 Gbps, the joint design of algorithms and application specific architectures is a major challenge that can benefit from new approaches to flexible algorithm and architecture integration. A new and unified approach for Application Specific Instruction Processor (ASIP) architectures for wireless systems is planned that is based on three components. First, emerging iterative receiver structures for high data rate multiple antenna (MIMO) systems that can be expressed as Factor Graphs will be analyzed. Then, the algorithm mapping to fixed application specific systems and the area, time, and power complexity for these fixed VLSI architectures will be explored. Third, since system flexibility is an important concern, architectures mapping efficiency and design exploration will be performed on programmable research ASIPs. The broader impact of this project will include web distribution through the Rice Connexions educational project, undergraduate student education through research in the Rice CMC-LAB, and also summer internships for underrepresented groups in the lab. Research interaction with Nokia and Texas Instruments scientists and with leading international research groups at the University of Oulu and Tampere University of Technology in Finland will create global coordination and contribution to new systems.

新一代移动无线设备正在出现，这些设备总是通过多种标准连接到不同的室内和室外环境。这个项目试图通过识别表达和翻译的共性来统一这些不同的算法和架构。随着无线数据速率超过100 Mbps并接近1 Gbps，算法和特定应用架构的联合设计是一个重大挑战，可以从灵活的算法和架构集成的新方法中受益。针对无线系统的专用指令处理器（ASIP）架构，提出了一种新的统一方法，该方法基于三个组件。首先，将分析可表示为因子图的高数据速率多天线（MIMO）系统的新兴迭代接收器结构。然后，算法映射到固定的应用特定的系统和面积，时间和功率的复杂性，这些固定的VLSI架构将探讨。第三，由于系统灵活性是一个重要的问题，架构映射效率和设计探索将在可编程研究api上进行。该项目的广泛影响将包括通过Rice Connexions教育项目进行网络分发，通过Rice CMC-LAB的研究对本科生进行教育，以及为实验室中代表性不足的群体提供暑期实习机会。与诺基亚和德州仪器的科学家以及芬兰奥卢大学和坦佩雷理工大学的领先国际研究小组的研究互动将创造全球协调并为新系统做出贡献。
