基于USB 2.0协议规范提出了一个USB 2.0设备控制器串行接口引擎SIE的IP核的设计,并内嵌8051软核作为其微控制器进行SoC设计。所设计的SIE核在FPGA开发板上经过验证。
Based on the USB 2.0 protocol specification, a USB 2.0 device controller serial interface engine (SIE) IP core design is proposed. The 8051 soft core is embedded as its microcontroller for SoC design. The designed SIE core is validated on the FPGA development board.
