机顶盒软件中间件SI模块和MAPI模块的设计分析

Design and Analysis of SI Module and MAPI Module of Set Top Box Software Middleware

机顶盒软件中间件的MAPI模块为硬件适配层,具有可移植性,可以提供上层对内存访问、实时操作系统、消息管理、设备驱动等接口,SI模块位于MAPI模块上,主要用来接收和管理SI表。文章首先对中间件SI模块和MAPI模块设计进行了分析,然后提出了集成测试方案,以期为同行业提供参考。

MAPI module STB software middleware for hardware adaptation layer, portability, can provide the upper access, real-time operating system, message management, device driver interface of memory, the SI module in MAPI module, mainly used to receive and manage the SI table. Firstly, the middleware SI module and the MAPI module design are analyzed, and then the integration test scheme is proposed, in order to provide reference for the same industry
