The PCI-X interface is an updated version of the connected PCI Bus (peripheral components Interconnect), still using traditional bus technology, but there are more wiring pins, at the same time, all connected devices share all available bandwidths, as described above. 1 What is the PCI-X and the original PCI interface is different: a change to the past 32-bit, the PCI-X uses 64-Bit Width to transmit data, s

　　About AmbaWith the development of deep submicron technology, the scale of IC chips is becoming larger and bigger. The digital IC has been developed from the design method based on sequential drive to the design method based on IP multiplexing, and has been widely used in SOC design. In the design of SOC based on IP multiplexing, the design of on-chip bus is the most important problem. For this reason, there are many on-chip

Two more questions are not resolved.(1) Prov_city_list.json after download, if it becomes an object of com.baidu.bus.f.b?In 3. In the 14th step of loading the city list, the member C of Hobject is assigned a value, and the type is COM.BAIDU.BUS.F.A, looking up how this object is generated:invoke-static {v0, p1}, Lcom/baidu/bus/net/a/b;->a (ljava/lang/string; lcom/baidu/a/a/m;) Lcom/baidu/bus/f/a;move-result

From: http://blog.csdn.net/flowingflying/article/details/5412711 The D-bus method is very important in mobile phone operating systems, including Linux-based operating systems such as maemo and moblin. It is estimated that andriod is also widely used. For more information about D-bus, see:Http://www.freedesktop.org/wiki/Software/dbus. Messages are transmitted between processes through D-

Separate bus communication Synchronous communication, asynchronous communication, and semi-synchronous communication start from the address and read/write command issued by the main module until the data transmission is complete. During the entire transmission cycle, the right to use the system bus is fully occupied by the master module and the slave module selected by the system

The content of many links in the latter article is also valuable.advantages and disadvantages of D-busLinux does not have a good IPC mechanism. Windows, MacOS, and Android have a "binder" subsystem. Linux has sockets, FIFO, shared memory and other mechanisms, which are not very good for the application layer. Kdbus attempts to create a mechanism that is similar to other systems for Linux

Synchronous bus communication The communication parties control data transmission on a unified time scale, which is called synchronous communication. This public clock can be sent to each component (device) by the CPU bus control component, or each component can have its own clock generator, which is usually issued by the CPU bus control component, all components

After all, it may involve hundreds of SQL queries. In addition, we only use the simplest SQL me

1. Bus) Bus refers to the standardized data exchange among computer components, which provides data transmission and control logic for each component in a common way. From another perspective, if mother board is a city, the bus is like a bus in the city, which can follow a fixed route, transmits bits that are continu

Relationship among bus, device, and driver Bus:As the connection channel between the host and peripherals, some buses are relatively standard and form many protocols. For examplePCI, USB, 1394, IIC, etc. Any device can select a suitable bus to connect to the host. Of course, the host may be the CPU itself. The memory is also connected to the host through the bus.The bus
