What is microprocessor cpu word length

This is the technology of the CPU core, a very esoteric theory.

The word length of a CPU usually refers to the width or number of bits of the data bus inside the CPU. We know that the CPU has internal data lines and external data lines, for example, the CPU internal data line of 8088 is 16 bits, and the external data line is 8 bits, then we say that its word length is 16 bits, and it is still a 16-bit processor, but when the CPU exchanges data with memory, it transmits data in an 8-bit mode. For example, the internal data line of Pentium4 CPU is 32 bits, and the external address line is 36 bits, and the external data line is 64 bits, and its word length is still 32 bits, so Pentium4 is still a 32-bit processor, not a 64-bit processor.

Similarly, if Intel's P4 processor works at the 200MHz external frequency, because the P4 uses 4 64-bit wide front-side buses, that is, we often say that the four-channel front-end bus, each channel works at a frequency of 200MHz, then the front-side bus frequency of the P4 becomes 4 200MHz = 800MHz, more precisely, the external frequency of the CPU describes the working frequency of the CPU external clock generator, that is, the working frequency obtained from the motherboard. The FSB frequency describes the data transfer rate of the CPU and the memory exchange data, that is, the external data transfer rate of the CPU.

Let's make a fuss upstairs.

Word length is the number of bits of binary numbers that the CPU can handle per unit of time (a certain amount of time).

A 32-bit CPU is a number expressed as a 32-bit binary number.

I don't know how the microprocessor CPU is different from this, but it should be.

64 bits.

Bits: Binary is used in digital circuits and computer technology, ** there are only "0" and "1", where either "0" or "1" is a "bit" in the CPU.

Word length: In computer technology, the number of binary digits that the CPU can process at one time in a unit of time (at the same time) is called the word length. Therefore, a CPU that can process 8-bit data is usually called an 8-bit CPU.

Similarly, a 32-bit CPU can process binary data with a word length of 32 bits per unit of time.

At present, the mainstream microcomputer CPU word length is 64 bits......Since the Pentium 4 and Athlon64 eras, 64-bit ...... has been popularizedIt's been more than ten years.

Now the mainstream 64-bit, Windows system is available in two versions: 32-bit and 64-bit.

CPU word length refers to the number of binary bits that the CPU can handle. The word length of a CPU is mainly determined by the number of bits of the combinator and register. For example, if a CPU has a 32-bit register and processes 32 binary bits at a time, then we say that the word length of this CPU is 32 bits, and we call this CPU "32-bit CPU".

The size of the word length directly reflects the data processing capacity of the computer, and the larger the value of the word length, the more binary bits of the data that can be handled at one time, the stronger the computing power. B-pre popular CPUs are mostly 32-bit or 64-bit.

The word length of the computer is determined by the CPU, which refers to the instruction length of the CPU. In the case of programming, the assembly part can be determined by the CPU, and most of it is determined by the compiler, regardless of the operating system. However, whether the compiler can be used or not is determined by the operating system, which means that the operating system only limits the CPU word length and does not depend on it.

Word length refers to the number of binary bits of the number involved in the operation at the same time, which determines the number of bits of registers, adders, data buses and other devices, and thus directly affects the cost of hardware, while the word length marks the calculation accuracy of the computer and the range of the data being represented. In order to facilitate the operation, many computers allow variable word length operations, such as half word length, whole word length, double word length, etc. The word length of a typical computer is between 8 and 64 bits, that is, a word is composed of 1 8 bytes.

The word length of a microcomputer is 8 bits, 16 bits, 16 bits, 32 bits, 64 bits, and so on.

The word length refers to the number of binary bits of the number that participates in the operation at the same time, and it determines the number of bits of registers, adders, data buses, etc.

The computer language expressed by the word length atlas system **, the instruction is a string composed of 0 and 1**, they have a certain number of digits, and are divided into a number of segments, and the encoding of each segment represents different meanings, for example, a computer word length is 16 bits, that is, there are 16 binary numbers to form an instruction or other information. The 16 zeros and 1s can be combined into various permutations and combinations, which can be turned into electrical signals through the wire, allowing the computer to perform a variety of different operations.

Word length is one of the main technical indicators of CPU, which refers to the number of binary bits that the CPU can process in parallel at one time, and the word length is always an integer multiple of 8, usually the word length of the PC is 16 bits (early), 32 bits, and 64 bits.

The calculated word length refers to the number of binary digits it can process at one time. The rate at which a computer processes data is naturally related to the number of bits it can process at one time and the speed of the calculation.

If one computer is twice as long as the other, even if both computers are at the same speed, the former can do twice as much work in the same amount of time.

Depending on the computer, there are two types of word lengths: fixed and variable. Fixed word length, that is, the word length is fixed no matter what the situation; Variable word length, then its length is variable within a certain range.

The word length of the CPU is **only "0" and "1", where either "0" or "1" is a "bit" in the CPU.
