基于IP复用的总线转换桥核的设计与研究

Design and Research of Converter Bridge Core Based on the IP Reuse

为了实现多总线协议之间的协议转换,根据片上总线的特性,通过状态机的使用来实现总线协议的转换.通过讨论片上总线标准、状态机的使用来建立总线转换桥的模型,并使用软件仿真的方法建立IP模型来验证总线转换桥的可用性.通过总线转换桥的设计实现了IP核在不同总线系统下的集成,从而实现基于不同总线协议的IP核在多总线体系下的复用.

In order to achieve conversion between the multi -bus protocol, according to the characteristics of On - Chip - Bus, through the use of state machine to achieve bus protocol conversion, this paper mainly discusses on - chip bus standard, the use of state machine to build bus converter bridge model, and the use of software simu- lation to establish the IP model for verifying bus converter Bridge availability. The designs of Bus Converter Bridge implement the integration of IP core in different bus protocol so as to achieve the IP of base on different bus protocol to reuse in a multi -bus system.
