基于ARM和STi5x数字网络机顶盒的设计

The Design of Digital Internet STB Based on ARM and Sti5x

论文设计了一款基于ARM9和Sti5518的数字网络机顶盒。文中对传统的数字机顶盒和数字网络机顶盒作了比较,通过比较发现,数字网络机顶盒在传统数字机顶盒的基础上增加了ARM9核CPU模块和双口RAM模块,数字网络机顶盒设计实现后,不仅能够完成传统数字机顶盒的所有功能,而且能够完成电视节目的存储、与互联网的连接,以及通过互联网能够完成的其它功能。文中同时给出的数字网络机顶盒的硬件逻辑设计。

The paper designs a digital internet STB based on ARM9 and Sti5518. There is a comparison between the traditional digital STB and digital internet STB in the paper, through the comparison we found that on the bases of traditional digital STB, digital internet STB has many advantages with module ARM9 CPU and double interface RAM, it can not only realize all the functions made by traditional digital STB, but also can make the store of digital TV program, finish connection with the internet and realize the other functions which made through internet. At the same time this paper gives the hardware logic design of digital internet STB.
