基于AMBA AXI总线的Crossbar互联设计与实现
esign and implementation of Crossbar interconnect Based on AMBA AXI protocol
为了解决高性能SOC模块间互联的瓶颈，本文设计了基于AMBA3.0 AXI协议的Crossbar结构和互联总线，该总线通过异步FIFO进行异步数据传输，在每个master和slave之间设置FIFO,保证了数据传输的准确性，减少了系统总线的延迟，仲裁使用了固定优先级和round robin两种模式，并且通过软件可以配置，该总线构架使用TSMC 65nm工艺进行综合，并且采用System Verilog 与VIP 搭建测试环境进行验证。该总线易于实现，可配置可扩展，有较高的吞吐量和较低的传输延迟。
In order to solve the bottleneck of SoC limited bus bandwidth This paper design an Crossbar interconnect infrastructure based on AMBA AXI protocol. This bus using asynchronous FIFO to cross different time domain, and implement FIFO on the between master and slave. which is used to keep data transfer accuracy, and reduce bus latency. The arbitration can be set to fixed priority or round robin, which is software configurable. This bus architecture has been implement in 65nm TSMC COMS library technology and verified by using System verilog based testbench and VIP[3], this bus architecture is easy to implement, flexible, configurable, and greatly improve the bus throughput and reduce the bus latency.
