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 M ediaTek 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 mand from serving base station. ? Layer 1 Driver: handles the DSP and Radio contro l -》 Drivers MCU 外围设备的驱动,如下: ? SIM: Subscriber Identity Module ? UART: Universal Asynchronous Receiver/Transmitter ? SPI: Serial Port Interface ? LCD: Liquid Crystal Display ? GPIO: General Purpose Input/Output ? GPT: General Purpose Timer ? RTC: Real Time Clock ? WDT: Watch Dog Timer ? PWM: Pulse Width Modulation ? Alerter ? Keypad ? PMIC: Power Management IC ? BMT:
