摘要

媒体应用，如图像处理、信号处理、视频和图形，需要很高的计算速率和数据带宽。流编程模型是描述这些应用程序的一种自然而强大的方式。在这个模型中表达媒体应用程序允许硬件和软件系统利用它们的并发性和局部性来满足它们的高计算需求。Imagine流编程系统是一套软件工具和算法，用于对流编程模型中的媒体应用程序进行编程。我们在各种媒体处理应用程序上实现了高计算率(每秒40 - 150亿次操作)和高效率(算术集群占用84-95%)的实时性能。

Media processing applications on the Imagine stream processor

Media applications, such as image processing, signal processing, video, and graphics, require high computation rates and data bandwidths. The stream programming model is a natural and powerful way to describe these applications. Expressing media applications in this model allows hardware and software systems to take advantage of their concurrency and locality in order to meet their high computational demands. The Imagine stream programming system, a set of software tools and algorithms, is used to program media applications in the stream programming model. We achieve real-time performance on a variety of media processing applications with high computation rates (4-15 billion achieved operations per second) and high efficiency (84-95% occupancy on the arithmetic clusters).
