Reconfigurable Computing: Bridging the Gap

可重构计算：桥接Gap可重构计算利用硬件调整其结构和功能以适应给定问题的能力。理论模型已经确立了其强大的功能和通用性，商业上可用的设备已经利用可重构来解决各种问题，但在理论和实践之间存在着巨大的差距。理论模型提出了一些不太可能实现的假设。实用的解决方案通常与设备特定的功能捆绑在一起，解决了给定的问题，但在开发广泛的技术时，除此之外几乎没有什么可提供的。这个项目试图通过将理论联系到现实中，同时从设备细节中抽象出解决方案来弥合这一差距。我们从两个方向来处理弥合理论和实践之间的差距的任务：(1)理论模型(主要是R-Mesh)和(2)商业可用硬件(主要是FPGA)。第一个方向将实际考虑实际问题(如总线延迟和功耗)，同时利用重新配置的力量。第二个方向将在实际硬件上构建问题解决方案(在图像处理和网络等领域)，目的是提取和应用一般原理。我们预计这些方向将为混合架构打开大门，这些架构寻求建立在两个平台的优势之上并填补对方的不足。

Reconfigurable Computing: Bridging the GapReconfigurable computing exploits the ability of hardware to adapt its structure and function to suit a given problem. Theoretical models have established its power and versatility, and commercially available devices have exploited reconfiguration in solutions to a variety of problems, yet a significant gap exists between theory and practice. Theoretical models make assumptions that are unlikely to be realizable. Practical solutions are often tied to device-specific features, solving the given problem, but offering little beyond that in developing broad techniques. This project seeks to bridge this gap by tethering theory in reality, while abstracting solutions from device details.We approach the task of bridging the gap between theory and practice from two directions: (1) theoretical models (primarily the R-Mesh) and (2) commercially available hardware (primarily FPGAs). The first direction will realistically account for practical considerations (like bus delay and power consumption), while exploiting the power of reconfiguration. The second direction will construct problem solutions (in areas like image processing and networking) on practical hardware with an aim of extracting and applying general principles. We expect these directions to open the door to hybrid architectures that seek to build on the strengths of the two platforms and fill each other's deficiencies.
