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. MS Executable Software, which is the software running on the MS, includes the following modules
- OS: Nucleus OS.
- L1 Protocol Stack: GSM physical layer.
- Drivers: device driver, like SIM, UART, GPIO, etc.
- L2/L3 protocol stack: GSM protocol stack layer.
- MMI: man-machine interface.
- WAP: Wireless application protocol.
- JAVA: J2ME Software
2. The Mobile Engineering Testing Architecture, also known as META
3. Catcher
－》OS
MediaTek采用Nucleus OS实时操作系统。KAL OS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。
－》L1 Protocol Stack
The physical layer or Layer 1 supports the transfer of bit streams on the radio medium according to the Technical Specifications of the 05-series. It provides service to upper layers and control the mapping and scheduling between the logical and physical channels. The TDMA framing and radio control parts are also implemented.
Layer 1 Asynchronous: handles the message request from upper layers and forward the result generated by layer 1 to upper layer.
Surrounding Cell Engine: handles the neighbor cell power measurement and neighbor cell synchronization information acquisition.
Layer 1 Control: handles the TDMA scheduling on the radio environment, including timing advance and power control command from serving base station.
Layer 1 Driver: handles the DSP and Radio control
