一种实用的动态可重构器件布线方法
A Practical Approach for Circuit Routing on Dynamic Reconfigurable Devices
摘要:
在具有大量逻辑资源和部分可重构性的新型FPGA中,通过在线路由来管理通信是一个新的具有挑战性的问题。片上网络(NoC)通常使用分组路由机制,其通常具有不安全的数据传输和网络接口开销。在本文中,这种动态片上网络的电路布线进行了研究,并提出和实现了一个实用的一维网络与高效的路由算法。此外,这一概念已被扩展到2维的情况下。实现结果表明,该网络具有面积开销小、性能高的特点。
英文摘要:
Management of communication by on-line routing in new FPGAs with a large amount of logic resources and partial reconfigurability is a new challenging problem. A Network-on-Chip (NoC) typically uses packet routing mechanism, which has often unsafe data transfers, and network interface overhead. In this paper, circuit routing for such dynamic NoCs is investigated, and a practical 1-dimensional network with an efficient routing algorithm is proposed and implemented. Also, this concept has been extended to the 2-dimensional case. The implementation results show the low area overhead and high performance of this network.
