　　萬用串列匯流排(Universal Serial Bus, USB)裝置是目前電腦配備的標準介面之一，在傳統的電腦介面中有很大的突破，它帶來了實用性和方便性，但也因為USB裝置局限在電腦系統上，這是美中不足的地方，本篇論文將探討，讓USB裝置在離開電腦系統時也可以做資料的傳輸動作，並說明USB的理論與實際設計的USB控制器來驗証。
　　本篇論文中，使用Xilinx公司所提供的FPGA發展板，做為程式設計驗証的環境，並以市面上的產品“隨身碟”做為應用，以FPGA、隨身碟和MP3 Decode，做為一個MP3即時撥放系統。

　　Nowadays, Universal Serial Bus (USB) is one of the essential interfaces in computers. It brings practicality and convenience. However, there is a shortcoming that USB must be confined to the computer systems. This thesis will introduce the USB theory and implement the USB host controller, which can transfer the data without the computer system.
　　In this thesis, we design a FPGA-based development board to verify the implementation of USB host controller. As an application system, the USB host controller (FPGA) will read the data from the Flash disk and then transfer it to the MP3 Decoder to form a MP3 real-time player system. The experimental results verify the effectiveness of the proposed MP3 play system.
