Abstract

As runtime reconfiguration is used in an increasing number of hardware architectures, new simulation and modeling tools are needed to support the developer during the design phases. In this article, a language extension for SystemC is presented, together with a design methodology for the description and simulation of dynamically reconfigurable hardware at different levels of abstraction. The library presented offers a high degree of flexibility in the description of reconfiguration features and their management, while allowing runtime reconfiguration simulation, removal, and replacement of custom modules as well as third-party components throughout the architecture development process. In addition, our approach supports the emerging concept of nested reconfiguration and split regions with a minimal simulation overhead of a maximum of three delta cycles for signal and transaction forwarding, and four delta cycles for the reconfiguration process.

NC 库：为嵌套式可重构硬件建模扩展 SystemC 功能

随着运行时重新配置技术在越来越多的硬件架构中得到应用，需要新的仿真和建模工具在设计阶段为开发人员提供支持。本文介绍了 SystemC 语言的扩展，以及在不同抽象层次上描述和模拟动态可重构硬件的设计方法。所介绍的库在描述重配置功能及其管理方面具有高度灵活性，同时允许在整个架构开发过程中进行运行时重配置仿真、移除和替换定制模块以及第三方组件。此外，我们的方法还支持嵌套重新配置和分割区域的新兴概念，并将信号和事务转发的模拟开销降至最低，最多不超过三个三角洲周期，重新配置过程不超过四个三角洲周期。

期刊介绍： TRETS is the top journal focusing on research in, on, and with reconfigurable systems and on their underlying technology. The scope, rationale, and coverage by other journals are often limited to particular aspects of reconfigurable technology or reconfigurable systems. TRETS is a journal that covers reconfigurability in its own right. Topics that would be appropriate for TRETS would include all levels of reconfigurable system abstractions and all aspects of reconfigurable technology including platforms, programming environments and application successes that support these systems for computing or other applications. -The board and systems architectures of a reconfigurable platform. -Programming environments of reconfigurable systems, especially those designed for use with reconfigurable systems that will lead to increased programmer productivity. -Languages and compilers for reconfigurable systems. -Logic synthesis and related tools, as they relate to reconfigurable systems. -Applications on which success can be demonstrated. The underlying technology from which reconfigurable systems are developed. (Currently this technology is that of FPGAs, but research on the nature and use of follow-on technologies is appropriate for TRETS.) In considering whether a paper is suitable for TRETS, the foremost question should be whether reconfigurability has been essential to success. Topics such as architecture, programming languages, compilers, and environments, logic synthesis, and high performance applications are all suitable if the context is appropriate. For example, an architecture for an embedded application that happens to use FPGAs is not necessarily suitable for TRETS, but an architecture using FPGAs for which the reconfigurability of the FPGAs is an inherent part of the specifications (perhaps due to a need for re-use on multiple applications) would be appropriate for TRETS.
