i2c bus

Platform is a virtual address bus, which is primarily used to describe on-chip resources on the SOC compared to PCI, USB. such as the integrated controller on the s3c2410 (LCD, Watchdog, RTC, etc.), the resources described by platform have one thing in common: the direct access on the CPU bus. The platform device is divided into a name (used in the driver bindings) and a series of resources such as address

Intel's QuickPath Interconnect technology is abbreviated as QPI, which translates to fast channel interconnection. In fact its official name is called the Csi,common System interface public interface, used to achieve direct interconnection between chips, rather than connecting to the North Bridge via FSB, directed at AMD's HT bus. Regardless of speed, bandwidth, the bandwidth of each stitch, power consumption and other specifications are beyond the HT

Many Ford and Mazda models (approximately since 2003-2004) is equipped with MS CAN bus, in addition to the regular HS CAN Bus. In contrast to HS can bus, MS can bus isn't supported by the stock ELM327, because Ms can is a manufacturer-specific solu tion and located on non-obd2 pins. However, ELM327 is very flexible too

This is the most commonly used, the most typical IIC bus connection mode.On the physical structure, the IIC system consists of a serial data line SDA and a serial clock line SCL. The host addre

There are two types of interconnection between the five parts of the computer system 1, using a separate line 2, each part connected to a set of public information transmission lines, called bus connections.Early computer-centric computing, when IO exchange information, all need to pass the operator, so that the operator stop operation, affecting CPU efficiency.At the same time, only one component is allowed to send information to the

1. The CPU performs an access to the external memory or I/O interface through Biu, which is called the CPU to perform a bus operation, according to a certain timing relationship. The cycle of performing a bus operation is called a bus cycle. In microcomputer system, the information interaction between CPU and other parts of the system is realized by various types

Brief introduction IBM Integration Bus is designed to address all integration requirements between back-end systems, from simple point-to-point connections to complex topology patterns such as ESB. It has a wide range of built-in connectors that support the integration of WEB services, files, databases, packaged applications such as SAP and Microsoft Dynamics CRM, as well as a variety of configuration and transformation options, such as graphical map

Duanxx STM32 learning: stm32 bus AMBA, AHB, APB A few days ago I looked at the main peripherals and circuit design of STM32. Today I began to look at the program design of STM32. Here I am using the STM32 library V3.5, so I am too lazy to see what registers The first problem encountered was the internal bus ahb and APB of STM32. Here I checked some information and recorded it.AMBAAMBA (Advanced Microprocess

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

BackgroundBased on the design of the bus, the design idea of the internal hardware of the computer (transmitting data via the bus) is borrowed. In distributed systems, there is a need for mutual communication and remote invocation between different subsystems, the direct way is "point-to-point" communication mode, but this will expose some obvious problems: the system tightly coupled , configuration and ref

Driven:Taking Sdio as an example, it uses Mmc_attach_sdio to match the driver and the device, and its essence is to match the Sdio_bus matching rules. In Mmc_attach_sdio, the MMC first matches a bus, that is, what bus to use for the MMC bus to process host. One thing to understand here is that in Sdio, for SD card memory MMC is a physical device, and for non-SD c
