Architectures for Emerging Applications

这项研究的广泛目标是开发和评估新兴的和未来的媒体处理应用程序的通用架构。这些应用程序预计需要的数量级更高的性能比今天的通用系统。一个关键的挑战是设计系统，将提供这样的媒体应用程序的性能改进，而不牺牲性能为更传统的applications.This研究利用了一个独特的机会，汇集架构研究人员和应用研究人员工作的技术基础媒体处理。 该研究主要集中在三类应用：（1）信号处理;具体而言，视频，图像，音频，语音处理和高速调制解调器，（2）无线通信，以及（3）虚拟环境和可视化。方法是使用模拟来开发对这些应用程序的行为的定量理解，并使用这种理解来开发新的体系结构技术。 图像和视频应用程序的初步定量研究已经激发了两个体系结构的方向：（一）设计的动态分区缓存，和（二）使用可重构逻辑的专门媒体功能的通用system.In过去，这样的体系结构研究一直受到阻碍缺乏访问的应用程序。 与工业界和其他研究人员的合作将克服这一障碍，并使未来的架构设计基于未来的应用。

The broad objective of this research is to develop and evaluate general-purpose architectures for emerging and future media-processing applications. These applications are expected to require orders-of-magnitude higher performance than available on today's general-purpose systems. A key challenge is to design systems that will provide such performance improvements for media applications, without sacrificing performance for more conventional applications.This research avails of a unique opportunity to bring together architecture researchers and applications researchers working on the technologies underlying media processing. The research focuses on three classes of applications: (1) signal processing; specifically, video, image, audio, speech processing, and high-speed modems, (2) wireless communication, and (3) virtual environments and visualization. The approach is to use simulation to develop a quantitative understanding of the behavior of these applications, and use this understanding to develop new architectural techniques. An initial quantitative study of image and video applications has motivated two architectural directions: (I) design of dynamically partitionable caches, and (II) use of reconfigurable logic for specialized media functions for a general-purpose system.In the past, such architectural research has been impeded by a lack of access to applications. The proposed collaboration with industry and other researchers will overcome this impediment and enable the design of future architectures based on future applications.
