TBOX：是汽车⽹络通讯的重要部件，⼀个带通讯功能的盒⼦，内含⼀张SIM卡，配套硬件还有GPS天线、4G天线等，可以提供位置定位、移动⽹络服务。简单理解它就是⼀个内置SIM卡的⽆线WIFI，不同之处是在于它还⽀持拨打电话，⼀般只能拨打常规号码，如：道路救援电话、⼚商客服电话、110等紧急电话。系统级芯片，低端的SOC就是在MCU的基础上加了一些定制化的功能，比如蓝牙协议，Zigbee协议，或者解码功能，和MCU功能上没什么大区别，其他的在差别就是在跑操作系统上。

高通平台smd分析及smem共享内存的创建笔记 tags ： linux driver 最近研究高通平台的音频相关，由于实在受不了没头没尾的数据，所以就顺便研究了一下smd以及smem，这篇博客就是一个笔记，比较杂乱，主要用来备忘！ 网上找到一些关于smd的文章，但是基本上都仅限于smd，只讲述了smd的channel相关，但是channel的内存到底哪里来的，smem到底是怎么回事好像...

在《Android SMD数据通信概述》一文中，我们了解到基于SMD的数据通信是以信道的形式作为一个设备存在的，作为一种双向信道，其接口的实现遵循Linux设备驱动规范。本文会结合SMD信道的实现简要介绍SMD信道的分配、打开、读取、写入、关闭等操作。 1．分配信道 SMD信道根据数据的类型可以分为流信道和包信道，其中包信道具有比流信道更强的流控制能力，包含头信息。在创建SMD信道时，

Linux驱动基础：MSM平台AP/CP通信机制
LoongEmbedded的专栏

概述MSM平台AP和CP封装到一个芯片，共享内容。所以之前也说过，高通的MSM解决方案中，CP的代码都是由AP放到指定地址的内存中以供CP运行。那上传完代码，CP开始跑之后，AP/CP之间的通信又是怎么弄的呢？ 其实也是在内存中开辟一段共享内存进行通信的。高通文档中有介绍以下三种。SMD : Shared Memory DriverSMEM : Shared Memory ManagerSMSM

想要用Unity3D做一个FPS游戏，可惜不会做模型，只好去找相关资源。真是少，好多模型网站都是坑爹的，注册完还不让下载。想想如果能用CS里边的模型就好了。上网搜了下资料，挺麻烦的，于是模型动作就不指望了，把模型转成我能用的静态的也行啊。 先是找了个CS的MDL模型的浏览器，(Half-Life Model Viewer )：（这些东西我会打成一个包，文章最后放一个下载地址） 可以看到里边的模

在Linux中，基于SMD的数据通信是以信道的形式作为一个设备存在的，作为一种双向信道，其接口的实现遵循Linux设备驱动规范。在Qucalcomm平台上，SMD的缓冲大小为8192bit，最大信道数为64，SMD的头大小为20bit。 SMD的相关代码实现主要位于aurora\msm\msm\arch\arm\mach-msm目录下。主要文件包括：smd.c、smd_nmea.c、smd_qm
