Thearithmetic logic unit(ALU) performs the arithmetic and logical functions that are the work of the computer. TheAandBregistershold the input data, and theaccumulatorreceives the result of the operation. Theinstruction registercontains the instruction that the ALU is to perform. For example, when ...
There are two main categories of CPUs: x86/x64 and ARM. While both perform the same basic functions, they have some key differences that may make one preferable over another depending on what type of device you are using. x86/x64 CPUs are designed for desktop computers, laptops, and serve...
所以,CPU需要提供 一些特定的指令,使得可以从内存中读取数据存入寄存器以及可以将寄存器数据存入内存。 此外还需要提供加法、减、not/and/or等基本运算指令,而乘除法运算都是推算出来的(支持的基本运算指令参见ALU Functions),所以乘除法的速度要慢的多。这也是算法里在考虑时间复杂度时常常忽略加减法次数带来的影响,而...
A CPU socket or CPU slot is an electrical component that attaches to a printed circuit board (PCB) and is designed to house a microprocessor. It is a special type of integrated circuit socket designed for very high pin counts. A CPU socket provides many functions, including providing a ...
英语翻译(1)Just as the CPU controls the computer(in addition to its other functions),the control unit controls the CPU.The unit generates the internal control signals that cause register to load data,increment or clear their contents,and output their contents as well as cause the ALU to perfo...

A switch maintains root and alternate ports based on the BPDUs periodically received on its CPU. If the upstream device cannot send BPDUs in a timely manner because its CPU is busy or the switch's CPU is too busy to process received BPDUs, the switch considers the original path to the ...

The central processing unit (CPU)is the computer’s brain. It handles the assignment and processing of tasks, in addition to functions that make a computer run. There’s no way to overstate the importance of the CPU to computing. Virtually all computer systems contain, at the least, some ...
