Intel 80386 microprocessor Memory Management

I. Memory ManagementMemory Management is a hardware mechanism. Microprocessor addressing physical memory on the bus address. However, in order to provide a program with a larger space than the physical storage capacity, the concept of virtual storage is introduced, which is implemented with the support of external storage (such as disks, generally, virtual addresses are called logical addresses. For MySQL 80386, there are both segment management and p

How the microprocessor is defined in the CPU

Since the invention of the transistor in human 1947span> years, more than 50 years of semiconductor technology experienced silicon transistors, integrated circuits, VLSI, very large scale integrated circuits and other generations, the rapid development of other industries are not. Semiconductor technology has a wide impact on society as a whole, so it is called "the seed of industry". CPU refers to the computer internal data processing and control of the processing process of the parts, with the

80X86 microprocessor structure and its working mode

80x86 is a series of microprocessors The microprocessor is also called the central Processing Unit, namely the CPU, is an integrated circuit chip. It is a core component of microcomputers.Since the microprocessor is the core of the microcomputer, it is necessary to discuss the microcomputer in a simple way first. Microcomputer: Microcomputer refers to the microprocesso

ARM microprocessor instruction set Overview (I) -- Detailed notes on ARM application system development

ARM microprocessor instruction set Overview The arm instruction set is load/storage-type. That is to say, the instruction set can only process the data in the register, and the processing results must be put back into the register, access to the system memory requires special loading/storage commands. ARM microprocessor instruction sets can be divided into six categories Jump command, data processing comm

Constants in ARM microprocessor

Constants in ARM microprocessor When learning constants in ARM microprocessor, I had been very ignorant. I checked them online and finally figured it out. I recorded them first. The original words in the book are::"A constant is an eight-digit constant that shifts the even digits (0, 2, 4, 8 ,... , 26, 28, 30. Fixed 32-bit instruction encoding during arm instruction. It is impossible to directly use 32-bi

9. Introduction of microprocessor

Microprocessor: Integrates all components into a single silicon chip. First microprocessor: Intel 4004. The most influential microprocessors: Intel8080, Motorola 6800. The above processors are referred to as single-chip microprocessors. Microprocessors, like single-chip microcomputer, have many pins. 8080 is characterized by a three pin is the supply voltage, the other pins are input, output, control signal
