Generally, the microcomputer (PC) is composed of the Main Board, CPU, memory, hard disk, and other devices, the single-chip microcomputer means that these devices are integrated into one chip (or some of them are implemented through external chip Extension). The single-chip microcomputer is also called a microcontrolle

Time -sharing of external extended address data bus with single chip microcomputerZz:http://doc.qkzz.net/article/7c2c3384-6ae9-49b2-8f56-200d87c1830a.htm 0 Share:-Li Ling "Abstract" This paper analyzes the bus timing of the external expansion of single-chip microcomputer, puts forward the problem of time-sharing of address and data bus when the system is connected by bus, and illustrates the design method o

The North Bridge Chip (Northbridge) is the most important component of the motherboard chipset, which is the closest chip on the motherboard to the CPU, which is responsible for contacting the CPU and controlling memory, by establishing a communication interface between the processor and the PCI bus, DRAM, AGP, and L2 cache. North Bridge Chip function No

After the chip sample stream comes back, all people are most concerned about whether the new functions are normal and whether the problems found in the old version are solved, this requires replacing the old chip in the verification system and re-running the system for verification. In the sample phase, various strange problems may occur due to the poor encapsulation and low yield rate. The

The 40 pins of a microcontroller can be divided into 4 categories: power , clock , control , and I/O pins .1. Power supply:⑴VCC-Chip power supply, connect to the + +;⑵vss-ground end;2. Clock:XTAL1, XTAL2-crystal oscillator circuit inverting input and output terminals. 3. Control lines: control lines Total 4, ⑴ale/prog: Address latch allow/on-chip EPROM programming pulse ①ale function: Used

No external cables or connectors and hot plug-n-play is sup

Advantages and disadvantages of embedding an operating system in a Single Chip Microcomputer As early as 1960s, some people began to study and develop embedded operating systems. However, it has not been mentioned more recently in China. The increasing importance of it in areas requiring real-time processing, such as communication, electronics, and automation attracts more and more attention. However, people often talk about some famous commercial

The architecture of the Da Vinci digital media on-chip system and the Linux Startup Process-Linux general technology-Linux programming and kernel information. The following is a detailed description. Da Vinci (DaVinci) digital media platform TMS320DM6446/3 adopts the ARM + DSP dual-core architecture. This article introduces the hardware structure of the chip and the Startup Process of the Da Vinci DMSoC and

This afternoon, I will lead the apprentice to learn about the installation and removal process. The following describes the problems encountered during the installation and removal process: North-South Bridge Chip: I. Position of the north-south bridge chip on the motherboard Generally, the North Bridge Chip is close to the CPU. The nanqiao

How do I swipe the chip card? The following small series for you to introduce the bank chip card how to brush, still do not understand a look at it. With the chip of the bank card, specific to see their own card media type to determine, chip bank card according to the type of media, divided into pure

Many friends buy u disk, only focus on the U disk capacity and price, and ignore the U disk chip quality problems. In fact, the chip is the core of the U disk components, in the purchase of USB stick before, we must understand the knowledge of the chip, the following for everyone to add. U disk storage of the core components are known as "Flash flash"

Single-chip microcomputer and (serial screen) touch screen communication based on Modbus Protocol (graphic)Introduction: Touch screen can be intuitive, vivid display of operating parameters and operating state, and through the touch screen screen can directly modify the system operating parameters, human-machine interaction is good. Touch screen and single-chip communication, the need for a single-

1-hour multi-thread structure application Generally, various control systems used by single-chip microcomputer have various interaction processes such as field data collection, control output, working status detection, and data transmission; the mismatch between the response speed of various peripherals and MCU is an important factor restricting the overall performance of the system. In the face of this interaction bottleneck, the use of time-based mu

My view of single chip microcomputerRecent health is not good, look back on such a few days to walk, now think, also to summarize the time. I have been in the field is very bad, a person, talking people do not have to work a person, sleep is a person. Very lonely. Of course it's a big part of the reason. I am a person who is eager to be loved, but a long time without. Now some of the professional Learning summary summary, in the future to see the youn

technology, including 70 NM evolution to 50 nm, and then evolve to 40 nm or 30 NM process technology, mobile phone customers will also have to redesign, but semiconductor products every 1 years of technology will be new, memory problems also drag on the speed of the introduction of mobile phones, So, like eMMC, the concept of wrapping all the memory and control chips that manage NAND flash on 1 MCP is becoming increasingly popular.eMMC design concept, is to simplify the use of memory in the pho

said ashamed, has always been, in school is also a lot of things, but instead of 51 single-chip computer This basic thing did not seriously to do, at the beginning of self-study 51 not one weeks, and then to Freescale 16 single-chip machine up, so that 51 has not thoroughly made a clear. is not as good as I know s12 monolithic computer what piece of RAM Ah, flash size Ah, instead is 51 not sure answer OH.

I am ashamed to say that I have been engaged in many things in school for a long time, but I did not seriously do the basic things of 51 single chip microcomputer. I had just learned 51 for more than a week, I switched to the 16-bit single-chip microcomputer of Apsara stack, so that 51 has not been thoroughly understood. It would be better for me to know exactly what kind of S12 single-
