1． MTK软件构架

参考文档：

MT6218_SW_ReleaseNote.pdf

MTK为MediaTek公司提供的GSM软件方案。

它包含5个部分：

－》L1协议

－》设备驱动

－》协议栈

－》MMI

－》WAP应用

MediaTek为用户提供3个工具：

－》Catcher

－》META

－》MCT

MTK软件架构图：

下面3个部分组成该软件方案：

   1.MSExecutableSoftware,whichisthesoftwarerunningontheMS,includesthefollowingmodules

 -OS:

NucleusOS.

 -L1ProtocolStack:

   2.TheMobileEngineeringTestingArchitecture,alsoknownasMETA

   3.Catcher

－》OS

   MediaTek采用NucleusOS实时操作系统。

KALOS层为MediaTek’s软件和Nucleus操作系统的接口。

它为任务提供许多系统服务函数，比如计时器，队列，内存管理，事件等等。

－》L2/L3/L4ProtocolStack

   这部分包含大量的GSM/GPRS需求以及提供一个优秀的GSM/GPRS平台给应用程序。

本地MMI和远程PC通过AT命令可以方便的使用该软件平台。

详细的结构如下：

 ?

RMI:

远程MMI，比如PC端，可以使用AT命令通过串口与协议栈进行通讯。
