开发基于现场可编程门阵列(FPGA)的应用程序通常是一项缓慢且需要多项技能的任务。支持应用程序开发的工具的研究也逐渐达到了较高的水平。本文介绍了一种方法,其目的是进一步提高水平的应用程序开发人员在开发基于FPGA的实现图像和视频处理应用程序的工作。开始的概念是一个系统的流式软协处理器。我们提出了一套软协处理器,实现了图像代数的一些关键抽象。我们的软协处理器设计为易于链接,并允许用户将其应用程序描述为一个简单的图。一个开发环境,称为SCoPeS的原型实现。即使在执行期间也可以修改应用程序,而无需重新合成。本文的结论与性能和资源利用率的结果为不同的实现的一个示例算法。我们的结论是,软协处理器的方法有可能提供更好的性能比软处理器的方法,并可以提高可编程性在专用HDL内核的特定领域的应用,同时实现竞争力的真实的时间性能和利用率。
Developing Field Programmable Gate Array (FPGA)-based applications is typically a slow and multi-skilled task. Research in tools to support application development has gradually reached a higher level. This paper describes an approach which aims to further raise the level at which an application developer works in developing FPGA-based implementations of image and video processing applications. The starting concept is a system of streamed soft coprocessors. We present a set of soft coprocessors which implement some of the key abstractions of Image Algebra. Our soft coprocessors are designed for easy chaining, and allow users to describe their application as a dataflow graph. A prototype implementation of a development environment, called SCoPeS, is presented. An application can be modified even during execution without requiring re-synthesis. The paper concludes with performance and resource utilization results for different implementations of a sample algorithm. We conclude that the soft coprocessor approach has the potential to deliver better performance than the soft processor approach, and can improve programmability over dedicated HDL cores for domain-specific applications while achieving competitive real time performance and utilization.
