What does the 32 bit in a 32 bit microcomputer mean?

The CPU of a 32-bit computer can handle up to 32 bits of data at a time, for example, its EAX register is 32 bits, although a 32-bit computer can usually handle both 16-bit and 8-bit data as well.

32-bit and 64-bit are said to be the maximum processing factors of the CPU.

That is, whether the data being processed is a 32-base number or a 64-based number.

This is designed to work with the operating system you're using.

It can process 32-bit binary numbers at the same time.

The CPU of a 32-bit computer can handle up to 32 bits of data. The number of digits of the operation

The registers can handle 32-bit binary at a time.

It is the number of bits of data processed at that frequency.

Refers to the size of the register.

The choice of c32 bits refers to the word length, which indicates the number of bits that the microprocessor can process in binary ** at a time. The internal data bus of most microprocessors is the same width as the external data pin bus width of the microprocessor. But there are a few exceptions.

With today's processors, these bit widths should be consistent. The same goes for 64-bit.

Data Development:

CPU development history: Our CPU has grown from 8-bit and 16-bit to 32-bit and 64-bit to the present.

When the CPU processes calculations, "data" and "instructions" are treated differently.

An 8-bit CPU can only process one 8-bit "data" or one 8-bit at a time"Directives"。For example:'00001101'.

For example, in the "+1" operation, you need to instruct the CPU to do the "+" before entering the "1" data to the CPU.

The advantage of an 8-bit CPU is that it has a simple design and a relatively fast processing speed.

The disadvantage is that the software design is complex and cumbersome. Not conducive to the development of computers.

Later, 16-bit CPUs were introduced, and we were able to process two bytes (16-bit) of data at a time, such as the "add 1" command. "Add" is an instruction that occupies 8 bits, and the remaining 8 bits can store the data "1".

A 32-bit CPU is even more convenient, and we can handle a command like a=a+b at a time.

Advantage: Simplifies the complexity of software design.

Disadvantages: The hardware design is more complex, and the computing speed is reduced.

How many bits of the microcomputer here refers to the word length of the machine, the word length is the number of bits of binary data that the computer computing parts can process at one time, the longer the word length, the stronger the processing power of the computer, it is a very important technical indicator to measure the performance of the computer, until the chip of the Pentium IV is 32 bits. Choose C

Machine word length.

How many bits of the microcomputer here refers to the word length of the machine, the word length is the number of bits of binary data that the computer computing parts can process at one time, the longer the word length, the stronger the processing power of the computer, it is a very important technical indicator to measure the performance of the computer, until the chip of the Pentium IV is 32 bits.

32 refers to the width of the instruction, and every time the data is stored, 32 is used, generally speaking, the wider the better.

c The so-called "32 bits" refers to the word length of the computer, and the longer the word length, the higher the computing accuracy of the computer.

In a computer, a byte is an indivisible basic unit of storage. When a computer processes data, the length of data that the CPU accesses, processes, and transmits through the data bus at one time is called a word, and a word usually consists of one byte and several bytes. Therefore, word length is an important indicator of computer performance, and the longer the word length, the stronger the performance.

The word length of different computers is not the same, and the commonly used word length is 8 bits, 16 bits, 32 bits, 64 bits, etc.

It should be c. Like our Shanghai Boji microcomputer protection device is also a 32-bit TI processor. The word length is usually constant in the number of bits of the CPU register in the computer system bus.

So. The higher the number of digits. means that the more powerful his processing power is.

The more reliable it is, too. I don't know if the microcomputer you are talking about here refers to the computer or the microcomputer protection device. But the answer should be C

32 refers to the word length of the computer. Computers with longer word lengths will also have higher calculation accuracy. A CPU that processes data with a word length of 8 bits is called an 8-bit CPU, and a 32-bit CPU processes binary data with a word length of 32 bits at the same time.

Answer] :d 32 bits refers to the word length, which indicates the number of scattered bits of binary ** that the microprocessor processes at a time. The width of the internal data buslet of most microprocessors is the same as that of the external data of microprocessors, so the answer is D.

Answer 32 of the 32-bit microcomputers. Refers to the word length, 32-bit CPU can process binary data with a word length of up to 32 bits at the same time, and 64 bits are also the same reason, that is, at the same time, the binary data with a maximum word length of 64 bits can be processed, and the computing accuracy of the computer with a longer word length will be relatively high, in general, most of the software is developed in the 32-bit architecture environment.

A 32-bit computer means that the CPU can handle up to 32 bits of data at a time.

Definition of bits: The smallest unit of data storage. In the binary number system of computers, bits, abbreviated as b, are also called bits, and each 0 or 1 is a bit.

8 bits is equal to one byte, that is, 8 bits = 32 bits = 4 bytes of data processed by the processor each time.

Thirty-two 32 refers to what the processor can handle at one time. The number of bits of the data.

The maximum number of binary bits of data that a CPU can process at a time.

The number of bits of 32 bits is worth the number of bytes, not the number of bits of address conversion, the bit is the smallest unit of computer execution, and the inner byte is the smallest unit of storage capacity, supporting 4GB memory, which is obviously related to storage, so the 32-bit system refers to 2 32bytes, that is, 4GB.

The addressing capability of a 32-bit system is 2 to the 32nd power, which is 4294967296b = 4194304KB = 4096MB = 4GB memory.

So the part other than 4G memory can't be handled.,Plus specialized.。

Priority is given to other hardware memory with higher genera, so in fact, 4G memory is not completely available!

A 32-bit microcomputer means that the CPU used by the computer is ()1 has 32-bit registers2, can process 32-bit binary numbers at the same time, 3 has 32 registers.

4. Able to process 32 characters at the same time.

Refers to x86 systems, that is, computers that use 32-bit CPUs and operating systems.
