First, I don't often give praise for support but I must say Travis, Karthik and Derek from TI have been extremely instrumental in getting my SRIO environment to work and bringing me up to speed on tips and tricks for SRIO.  It has been very nice to s…

C6678->SRIO和Virtex6->FPGA   设计的板子到了SRIO调试阶段了,在板子上,一片V6和两片6678通过4XSRIO互联,中间没有Switch,总算搞定了相互之间的通信. 首先,感谢Ti论坛提供的SRIO程序范例,但是其硬件平台是EVM板,更多的只能用于loopback测试,但是可以在其基础上修改. 1.初始化DSP的SRIO,主要是对SerDes进行配置,然后是Lane和Speed的配置,最后需要等待FPGA的LinK建立,我们在建立时候碰到一点困难,每次建立并不都是4…

App层 从大拇哥Click CallButton开始手机便已明白,主人这是要打电话.当然,你可以选择直接拨号,也可以通过ContactList,或者从通话记录着手.这些都只是UI的设计不同而已,终归都会有一个统一的入口开始Calling.这个汇合点就是: android:targetActivity="OutgoingCallBroadcaster" 这是一个独立的Activity,你可以设计各种花里胡哨的拨号方式.Activities,而后通过startActivity跨应用访问来…

One-Way and Duplex Communication A message exchange pattern describes the way messages are sent between applica-tions. There are three classic message exchange patterns: request-reply, one-way, and duplex (callbacks). Figure 3-7 illustrates these pat…

A context switch (also sometimes referred to as a process switch or a task switch) is the switching of the CPU (central processing unit) from one process or thread to another. A process (also sometimes referred to as a task) is an executing (i.e., ru…

1.C6678 Keystone1架构的GbE switch subsystem如图所示: 2.从图中可以看到MAC层与物理层PHY芯片的连接接口是由SGMII+SerDES构成,SGMII是以太网MAC与PHY之间的媒体接口,SerDES为可编程的串行接口,为差分输入输出. 3.网上很多资料说SGMII接口电器特性与SerDES兼容,可以配置成串行接口,可以直接与PHY芯片连接,但是C6678为什么设计成SGMII+SerDES这种模式? 4.解释3的原因:SGMII只是一个普通的高速串行接口…

Communication with ROS through USART Serial Port We always need to communicate with ROS through serial port as we have many devices like sensors, touch-screen, actuators to be controlled through USART serial protocol. After some investigation, I foun…
