How many bits of binary data can be processed?

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

When the CPU in a microcomputer performs arithmetic operations and logical operations, the binary data lengths that can be processed are 8 bits, 16 bits, 32 bits, and 64 bits.

In the computer field, word is a term used to represent its natural data unit for a specific computer design, and is a fixed length used to represent a one-time transaction. . The number of bits in a word, that is, the word length, is an important feature in the structure of computer systems.

The computer word length refers to the number of binary digits that the CPU can process in parallel at one time. A CPU that processes 8-bit data is usually called an 8-bit CPU. A 32-bit CPU processes 32-bit words at the same time. bits of binary data. Each binary 0 or 1 is the smallest unit that makes up the binary system, called a bit.

The word length is always an integer multiple of 8. Usually the word length of the PC is 8 bits (early), 16 bits (early), 32 bits, and 64 bits.

Word length has a great relationship with the functions and uses of the computer and is an important technical indicator of the computer. The word length directly reflects the calculation accuracy of a computer. In order to adapt to different requirements and coordinate the relationship between calculation accuracy and hardware cost, most computers support variable word length operations, that is, half word length and full word length can be realized in the machine. (or single word length) and double word length operations. All other indicators being equal, the larger the word length, the faster the computer can process data. The word lengths of early microcomputers were generally 8-bit and 16-bit, and most 386 and higher processors were 32-bit. Most computers on the market have 64-bit processors. The word length is determined by the number of data bus lines in the microprocessor's external data path.
