This article will explain in detail how many bits of binary data can be processed in a microcomputer. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

When CPU performs arithmetic and logic operations in a microcomputer, the length of binary data that can be processed is 32 bits and 64 bits. The number of binary bits that CPU can process in parallel at one time is word length, which is always an integral multiple of 8. The commonly used word lengths are 8 bits (early), 16 bits (early), 32 bits and 64 bits.

The operating environment of this tutorial: windows7 system, Dell G3 computer.

When CPU performs arithmetic and logic operations in a microcomputer, the length of binary data that can be processed is 8 bits, 16 bits, 32 bits and 64 bits.

In the computer field, for a particular computer design, word is a term used to represent its natural unit of data and a fixed length used to process transactions at one time. The number of digits of a word, that is, word length, is an important feature in the structure of a computer system.

Computer word length refers to the number of binary bits that CPU can process in parallel at one time. CPU that deals with 8-bit data is usually called 8-bit CPU,32-bit CPU, which deals with 32-bit binary data at the same time. Each 0 or 1 of the binary is the smallest unit that makes up the binary, called a bit.

Word length is always an integral multiple of 8, usually 8-bit (early), 16-bit (early), 32-bit, 64-bit on PC.

The word length has a great relationship with the function and use of the computer, and it is an important technical index of the computer. Word length directly reflects the calculation accuracy of a computer. in order to meet different requirements and coordinate the relationship between operation accuracy and hardware cost, most computers support variable word length operation. that is, half-word-length, full-word-length (or single-word-length) and double word-length operations can be realized in the machine. Other indicators are the same, the larger the word length, the faster the computer can process the data. The word length of early microcomputers was generally 8-bit and 16-bit, while 386 and higher processors were mostly 32-bit. Most of the computers on the market have 64-bit processors. The word length is determined by the total number of data lines of the external data path of the microprocessor.
