新型数字机顶盒的管理模块设计

Design of New Digital STB Management Module

从家用数字业务的市场需求出发 ,提出新型数字机顶盒的管理模块的设计方案。首先详细讨论中心管理模块的设计方案及其核心芯片———基于ARM7内核的S3C4 5 10B ,并给出硬件模块接口图 ;然后介绍采用uClinux嵌入式操作系统的软件体系结构和在uClinux系统下的管理模块与电脑终端实现数据交互的操作流程。

This paper proposes a design of management module of n ew digital set-top box from market demand of domestic digital services. At firs t, it details the design scheme of central control module and kernel chip-S3C451 0B, which based on ARM7 kernel, and provides the charts of hardware module inter face; secondly, it introduces the software architecture adopting the embedded op eration system of uClinux and the operation flow of the realization of data inte raction between management module and computer termination in uClinux system.
