隨著資訊家電的發展，現今的消費者正享受著高度資訊化的生活所帶來的便利，追求著高品質低價格、易攜性、有著強大功能卻穩定耐用的資訊產品。而以研發者的角度來看，為了營造最多的利潤，則需要成本低廉、軟體研發容易、硬體有著延續性及多樣性的資訊開發平台。在眾多考量下TMS320DSSC25開發平台因此應孕而生。

本篇論文針對TMS320DSSC25開發平台，從硬體功能的驅動及其應用程式作出一套系統架構，特別針對通用序列埠(universal serial bus)連接部份作深入的研究，在TMS320DSC25上實作一大量儲存裝置的驅動程式，使TMS320DSC25扮演一通用序列埠(universal serial bus)裝置端，而透過通用序列埠介面與通用序列埠主機端溝通，達到資料儲存與分享的功能，使得整體TMS320DSSC25嵌入式系統的開發更加完善並且更具擴充性。

With the growth of information technology, the developments of communication equipment become mobile and complicated. Now consumers are able to enjoy convenient life by using such developments. People always seek the information products which are with high quality, low price, portable, powerful, and stable. On the other hand, in order to create more benefit from low cost, Researcher and designer keep looking for some developing systems which are inexpensive and easy to develop software. Moreover, with the features of continuity and versatileness, is selected as platform in this study.
In this thesis, we studied the detailed functions of the TMS320DSSC25 operation system as well as the drivers and application of its hardware. We also go deep into the part of universal serial bus transmission which is deficient in the kernel. Then we implement the mass storage device driver to meet the requirements of storage of data and sharing of data .Finally, we make the whole embedded system on TMS320DSC25 workable
