Abstract

In this paper we present a scalable wormhole switch architecture with a credit based guaranteed service implementation. By means of credits for a service guarantee the architecture is also able to deal with mesochronous GALS systems. We extended a regular wormhole switch architecture with a control unit for service configuration during run-time and modified the arbitration policy. These changes result in a marginal area overhead per switch of approximately 4\%. Thus our new architecture provides a simple solution to implement service guarantees without limitation to a fully synchronous system. We synthesized our design with a 65nm technology and achieved a clock frequency of 1GHz. Due to the high clock frequency we are able to get a channel throughput of more than 4GB/sec whereas the total design complexity is 30k gate equivalents.

具有基于信用的保证服务支持的NoC交换机，适用于GALS系统

在本文中，我们提出了一种可扩展的虫洞交换机架构，该架构具有基于信用的保证服务实现。通过服务保证的信用，该体系结构还能够处理中同步GALS系统。我们扩展了常规的虫洞交换机架构，在运行时使用控制单元进行服务配置，并修改了仲裁策略。这些变化导致每个交换机的边际面积开销约为4%。因此，我们的新架构提供了一个简单的解决方案来实现服务保证，而不局限于完全同步的系统。我们采用65nm技术合成了我们的设计，并实现了1GHz的时钟频率。由于高时钟频率，我们能够获得超过4GB/秒的通道吞吐量，而总设计复杂性为30k门等效。
