USB设备控制器IP核系统设计及FPGA实现

System Design and FPGA Implementation ofthe IP Core of USB Device Controllers

本文针对USB设备单芯片设计方法,介绍一种USB设备控制器IP核系统的设计,提出SIE核心控制流程,能满足设备控制器最大限度精简指令,同时对USB设备控制器如何屏蔽USB协议做了部分探讨,并简述了FPGA验证。

Based on a single chip design concept, the paper introduces the design of the IP core for USB device controllers. It presents the key flowchart of SIE and simplifies the IRQ （Interrupt Requests） scheme. In addition, some methods are discussed to shield the USB protocol , and the FPGA verification is introduced.
