摘要
USB OTG双模控制器主从控制状态机是支持在两个USB设备之间直接互传数据的重要功能模块。在充分分析OTG补充规范的基础上,提出了USB OTG双模控制器主从控制状态机的实现方法,完成了OTG双模控制器IP核的设计,通过了基于Parterre SoC平台的FPGA验证,结果证明了设计的正确性。该IP支持UTMI+接口,可以广泛应用于包含USB功能的SoC开发。
As an important module of USB On-The-Go dual-role controller, the host/device control FSM helps two USB devices to communicate with each other directly. Implement method of host/device control FSM for USB OTG dualrole controller is proposed in this paper in detail, and design of the USB OTG dual-role controller IP is also completed. The simulate results demonstrate the correctness of the design after passed functional verification which based on Parterre SoC platform. With a standard UTMI＋ interface, the IP is suitable for SoC design with USB module widely.
