Unifying Application Specific Processors for Communication Systems

约瑟夫·R·卡瓦里亚罗威廉·马什·赖斯大学统一通信系统专用处理器新一代移动无线设备始终通过多种标准连接，用于不同的室内和室外环境。这个项目寻求通过识别表示和翻译中的共性来统一这些不同的算法和体系结构。随着无线数据速率超过100 Mbps和接近1 Gbps，算法和特定于应用的架构的联合设计是一个重大挑战，可以受益于灵活的算法和架构集成的新方法。针对无线系统的专用指令处理器(ASIP)体系结构，计划了一种新的统一方法，该方法基于三个组件。首先，将分析用于高数据速率多天线(MIMO)系统的迭代接收器结构，这些结构可以表示为因子图。然后，将探讨到固定应用特定系统的算法映射以及这些固定VLSI体系结构的面积、时间和功耗复杂度。第三，由于系统灵活性是一个重要的关注点，将对可编程研究ASIP进行架构映射效率和设计探索。该项目的更广泛影响将包括通过莱斯连接教育项目的网络分发，通过莱斯CMC实验室的研究进行本科生教育，以及在实验室为代表不足的群体进行暑期实习。与诺基亚和德州仪器公司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产生全球协调，并为新系统做出贡献。

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.
