片上网络(NoC)是一种新兴的处理大型片上系统通信的范例。这个项目研究的能力原型 异步片上系统。 在标准FPGA上实现异步电路是高度实验性的,因此该项目的第一部分是建立一个设计 如何在FPGA上实现异步电路。项目中 成功地开发了一种用于FPGA的异步尽力而为NoC。 NoC实现由路由器和网络适配器组成,并使用4阶段捆绑数据握手协议实现。核心连接 使用OCP接口连接到网络。为了展示NoC, 在一个小型多处理器原型中实现, 网络
Network-on-chip (NoC) is an emerging paradigm for handling the communication in large system-on-chips. This project investigates the ability to prototype asynchronous NoCs on FPGAs. The implementation of asynchronous circuits on standard FPGAs is highly experimental, therefore the rst part of the project has been to establish a design ow for the implementation of asynchronous circuits on FPGAs. In the project an asynchronous best-effort NoC for an FPGA has been successfully developed. The NoC implementation consists of a router and network adapters and is implemented using a 4-phase bundled data handshake protocol. Cores connects to the network using an OCP interface. To demonstrate the NoC it has been implemented in a small multi-processor prototype using a mesh topology for the network.
