USB OTG IP核中AMBA总线接口的设计

AMBA总线接口是USB OTG IP核中用于与外部MCU进行数据通信的接口。在完成USB OTG IP核系统框架设计并充分分析AMBA总线规范的基础上,提出AMBA总线控制状态机的实现方法,完成AMBA总线接口的设计,通过基于Xilinx FPGA验证,仿真实验结果证明设计的正确性,可用于包含USB功能的SoC开发中。

Design of AMBA Bus Interface in USB OTG IP Core

AMBA bus interface is used for data communication with external MCU in a USB OTG IP core.After completion of the design of system framework of USB OTG IP core and analysis based on the AMBA bus specification,an implement of AMBA bus control state machine is proposed in detail,and the design of AMBA bus interface is also completed.The simulate results demonstrate the correctness of the design after passing functional verification which based on Xilinx FPGA,the IP is suitable for SoC design with USB module.
