| | Arithmetic logic unit - Wikipedia, the free encyclopedia |
 | | ALUs are capable of calculating the results of a wide variety of basic arithmetical computations. | | | The arithmetic logic unit/arithmetic-logic unit (ALU) of a computer's CPU is a part of the execution unit, a core component of all CPUs. | | | Virtually all modern computer ALUs use the two's complement binary number representation (whereas some early computers used either one's complement or sign-magnitude format). |

| | Central processing unit - Wikipedia, the free encyclopedia |
| | The phrase "central processing unit" is, in general terms, a functional description of a certain class of logic machines that can execute complex computer programs. | | | A central processing unit (CPU), or sometimes simply processor, is the component in a digital computer that interprets and executes instructions and data contained in software. | | | The ALU contains the circuitry to perform simple arithmetic and logical operations on the inputs (like addition and bitwise operations). |

| | Information processor - US Patent 6810474 |
| | An address of the instruction terminated by the ALU 109 is inputted into the history cache 111 as the instruction address 212 of the executed instruction, and the data of the execution result is inputted as the ALU-DATA 211. | | | However, when a branch instruction is executed by an ALU 109 and the address of the instruction to be executed is changed, a new address of the instruction is inputted into the counter 110 by a selector 114. | | | The HEU 117 is an arithmetic and logical unit that only outputs the past execution result of the instruction, as it is, omitting the actual instruction execution. |

| | Among other tasks carried out are the control of input and output devices and the passing of data to the Arithmetic/Logical Unit for computation. | | | It is worth noting here that the only operations that the CPU can carry out are simple arithmetic operations, comparisons between the result of a calculation and other values, and the selection of the next instruction for processing. | | | The Control Unit -- controls the fetching of instructions from the main memory and the subsequent execution of these instructions. |
