them. Two mainstream chips The core processors of arm9-and MIPS are currently mainstream. The Cache capacity is 8 K or less, which is usually 16 K, and 32 K or more is large. The arm9-architecture has a common 920 T/922 T/940T and a reinforced 926E/946E/966E. MIPS is divided into 2 K, 3 K, 4 K, and 5 K. The performance and structure of different models vary greatly. ARM and Product Introduction ARM is a well-known enterprise in the microprocessor ind

Dsp: DSP (Digital singnal processor) is a unique microprocessor, with its own complete instruction system, is a digital signal to process a large number of information devices. A digital signal processor in a small chip includes a control unit, an operating unit, a variety of registers and a certain number of storage units, etc., in its periphery can also be connected to a number of memory, and can communicate with a certain number of external devices

processor Selection The core component of the embedded system is various types of embedded processors. According to incomplete statistics, the total number of embedded processors worldwide has exceeded more than 1000, and the popular architecture has 30 series. However, unlike the global PC market, there is no microprocessor or microprocessor company that can take the lead in an embedded system. In 32-bit

Design of CPLD Visual System Based on Image Sensors 10:23:31 Source: MCU and embedded system Author: Beijing University of Aeronautics and Astronautics Liu junmu Previously, research on visual systems has become a hot topic, and some systems have been developed for reference. However, these systems are mostly based on PCs. Due to the complexity of algorithms and hardware structures The application is restricted. After the above system collects image data, the visual processing algorithm is imple

Principle and application of microcomputer exercise library and answer Exercises and Exercises 1 The 1th Chapter Introduction 1. Computers are divided into those categories. What are the characteristics of each. A: Traditionally divided into three categories: large mainframe, small machine, microcomputer. Large-scale mainframe is generally high-performance parallel processing system, large storage capacity, the ability to handle things, can provide services for many users. Minicomputer has cert

1, the definition of embedded system (1) Definition: application-centric, computer-based, software and hardware can be cut to adapt to the application system to function, reliability, cost, volume, power consumption requirements of the dedicated computer system.(2) 4 stages of embedded system development: No operating system stage, simple operating system stage, real-time operating system stage, Internet-facing stage.(3) Intellectual property core (IP Core): With intellectual property rights, f

of memory is only two kinds of reading and writing (for some CPUs and operations, but we only talk about reading and writing, because there are two enough). There are so many memory units, I have to read or write when I have to tell people what we want is the internal deposit, this is going to pass the number, for 4GB memory, the number is from 0 to 4 billion-1 (note is starting from 0, in the computer or C language, a lot of things are starting from 0), this number is the address. Read is to p

(i) OverviewBaseband digital processing functions and basic peripheral functions of mobile phones are concentrated on the single chip system (SOC), the basic architecture of the microprocessor + Digital signal processor (DSP) structure, microprocessor and DSP processing capacity has been enhanced. The microprocessor is the control center of the entire chip and ru

ARM processor status The ARM microprocessor generally has two working states and can be switched between them: The first type is the arm State. At this time, the processor executes the 32-bit arm command; The second is the thumb State. At this time, the processor executes the 16-bit half-aligned thumb command. During the execution of a program, the microprocessor can switch between the two working states at

possible capacity of memory, which should be used to store program code and program execution of the data generated, these instructions in memory is stored sequentially, and can be addressed by the program counter, but allow conditions to jump. This is the stored program concept (Stored-program concept).11 development of the computerChip: A silicon wafer containing integrated circuits that is small in size and often part of a computer or other electronic device. IC entities are often present in

power. Multi-core technology is the inevitable development of the processor in the last 20 years, the main factors that drive the performance of microprocessor are two: the rapid progress of semiconductor process technology and the continuous development of the system structure. Each progress of semiconductor process technology brings forward new problems for the research of microprocessor architecture, an

With the growing number of mobile device platforms, and even the momentum to replace the desktop platform, the word "arm" is increasingly appearing in people's eyes, especially on mobile phones or tablet processors, but never see arm's processor, but "the adoption of ARM's latest architecture" processor. In fact, ARM (adanced RISC machines) is not only a generic term for a processor, but also a company name, which can also be considered a technical name. 1991 ARM Company was established in Camb

1. Bus: we know that a circuit is always made up of components connected by wires. In a analog circuit, the connection is not a problem because the devices are generally in a serial relationship, there are not many connections between each device, but the computer circuit is different. It is based on a microprocessor. Each device must be connected to a microprocessor, and the work of each device must be coo

powerful functions, it has the following Disadvantages: (1) the touch screen input method provided is too fine and not suitable for on-site operations by staff; (2) Poor Display Effect of tft LCD screen under strong light, it consumes a lot of power and cannot work at low temperatures (less than 0 ℃). Therefore, it is not suitable for outdoor work. (3) it is costly to use Microsoft's commercial system WinCE.This article introduces a portable RFID Information Collection and Processing System Bas

Windows Live Messenger has been pretty hot lately. But very annoying is the new version of MSN with the old, with the advertising bar. You can go to the Internet to download patches to remove these ads. But I don't like to use patches, so I found a manual way to advertise on the Internet, this method is suitable for 8 series. Locate the Msgsres.dll file under C:\Program files\msn Messenger, and open it with Reshacker or restorator. To remove the Chat dialog box ad, open resource number
