L1层逻辑图

L1各部分功能
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 ：处理相邻小区的功率测量以及同步信息获取
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
L1驱动：DSP 以及无线控制

设备驱动
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

模块介绍
RMI Remote MMI，PC端通过UART口与协议栈进行通讯
FMI Feature rich MM
L4 MMI通过L4与gsm/gprs协议栈进行通讯，包括以下子模块
ATCI: AT

Command Interpreter, 解释来自PC端的命令并命令L4做相应的动作
L4A: L4 adaptation Layer, MMI与L4A通过消息通信
L4C: L4 Control entity, 处理所有的应用程序请求和响应
UEM: User equipments adaptation, 驱动相关的适配层

安全性管理以及STK
CSM: Circuit switching protocol stack management电路交换协议栈管理
