  2. Arithmetic logic unit - Wikipedia

    en.wikipedia.org/wiki/Arithmetic_logic_unit

    In computing, an arithmetic logic unit (ALU) is a combinational digital circuit that performs arithmetic and bitwise operations on integer binary numbers. [ 1 ] [ 2 ] This is in contrast to a floating-point unit (FPU), which operates on floating point numbers.

  3. Adder (electronics) - Wikipedia

    en.wikipedia.org/wiki/Adder_(electronics)

    In many computers and other kinds of processors, adders are used in the arithmetic logic units (ALUs). They are also used in other parts of the processor, where they are used to calculate addresses , table indices , increment and decrement operators and similar operations.

  4. Datapath - Wikipedia

    en.wikipedia.org/wiki/Datapath

    A data path is a collection of functional units such as arithmetic logic units (ALUs) or multipliers that perform data processing operations, registers, and buses. [1] Along with the control unit it composes the central processing unit (CPU). [1] A larger data path can be made by joining more than one data paths using multiplexers.

  5. Control unit - Wikipedia

    en.wikipedia.org/wiki/Control_unit

    The control unit (CU) is a component of a computer's central processing unit (CPU) that directs the operation of the processor. A CU typically uses a binary decoder to convert coded instructions into timing and control signals that direct the operation of the other units (memory, arithmetic logic unit and input and output devices, etc.).

  6. 36-bit computing - Wikipedia

    en.wikipedia.org/wiki/36-bit_computing

    In computer architecture, 36-bit integers, memory addresses, or other data units are those that are 36 bits (six six-bit characters) wide. Also, 36-bit central processing unit (CPU) and arithmetic logic unit (ALU) architectures are those that are based on registers, address buses, or data buses of that size. 36-bit computers were popular in the early mainframe computer era from the 1950s ...

  7. 128-bit computing - Wikipedia

    en.wikipedia.org/wiki/128-bit_computing

    In computer architecture, 128-bit integers, memory addresses, or other data units are those that are 128 bits (16 octets) wide.Also, 128-bit central processing unit (CPU) and arithmetic logic unit (ALU) architectures are those that are based on registers, address buses, or data buses of that size.

  8. Von Neumann architecture - Wikipedia

    en.wikipedia.org/wiki/Von_Neumann_architecture

    A von Neumann architecture scheme. The von Neumann architecture—also known as the von Neumann model or Princeton architecture—is a computer architecture based on the First Draft of a Report on the EDVAC, [1] written by John von Neumann in 1945, describing designs discussed with John Mauchly and J. Presper Eckert at the University of Pennsylvania's Moore School of Electrical Engineering.

  9. Transport triggered architecture - Wikipedia

    en.wikipedia.org/wiki/Transport_triggered...

    The interconnection network is used to transfer the current values of registers r1 and r2 to the function unit that is capable of executing the add operation, often called ALU as in Arithmetic-Logic Unit. Finally, a control signal selects and triggers the addition operation in ALU, of which result is transferred back to the register r3.
