MTK软件构架
参考文档:
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.
L1或者叫物理层,提供物理介质上的bit流传输,遵循 gsm 技术05系列规范;为上层软件提供服务,且控制逻辑信道到物理信道的映射和安排无线控制以及TDMA桢.
􀁺 Layer 1 Asynchronous: handles the message request from upper layers and forward the result generated by layer 1 to upper layer.
L1异步逻辑:处理上层软件的消息请求,发送L1处理后的结果给上层软件
􀁺 Surrounding Cell Engine: handles the neighbor cell power measurement and neighbor cell synchronization information acquisition.
Surrounding Cell Engine :处理相邻小区的功率测量以及同步信息获取
􀁺 Layer 1 Control: handles the TDMA scheduling on the radio environment, including timing advance and power mand from serving base station.
L1层控制:处理无线环境中的TDMA时序安排,包括定时提前以及来自基站的功率控制
􀁺 Layer 1 Driver: handles the DSP and Radio control
L1驱动:DSP 以及无线控制
-》Drivers
设备驱动支持所有MCU(微处理器单元)外设的控制功能
本模块处理一些用户可见操作的一些设备,如键盘,LCD等
通过L4层接口,访问寄存器来控制外设
MCU外围设备的驱动,如下:
􀁺 SIM: Subscrib
