  2. Carry-skip adder - Wikipedia

    en.wikipedia.org/wiki/Carry-skip_adder

    The critical path of a carry-skip-adder begins at the first full-adder, passes through all adders and ends at the sum-bit .Carry-skip-adders are chained (see block-carry-skip-adders) to reduce the overall critical path, since a single -bit carry-skip-adder has no real speed benefit compared to a -bit ripple-carry adder.

  3. Bitwise operation - Wikipedia

    en.wikipedia.org/wiki/Bitwise_operation

    A bitwise AND is a binary operation that takes two equal-length binary representations and performs the logical AND operation on each pair of the corresponding bits. Thus, if both bits in the compared position are 1, the bit in the resulting binary representation is 1 (1 × 1 = 1); otherwise, the result is 0 (1 × 0 = 0 and 0 × 0 = 0).

  4. Circular shift - Wikipedia

    en.wikipedia.org/wiki/Circular_shift

    In computer programming, a bitwise rotation, also known as a circular shift, is a bitwise operation that shifts all bits of its operand. Unlike an arithmetic shift , a circular shift does not preserve a number's sign bit or distinguish a floating-point number 's exponent from its significand .

  5. Zhegalkin polynomial - Wikipedia

    en.wikipedia.org/wiki/Zhegalkin_polynomial

    bitwise operation "Exclusive OR" The most economical in terms of the amount of computation and expedient for constructing the Zhegalkin polynomial manually is the Pascal method. We build a table consisting of columns and + rows, where N is the number of variables in the function. In the top row of the table we place the vector of function ...

  6. Arithmetic logic unit - Wikipedia

    en.wikipedia.org/wiki/Arithmetic_logic_unit

    In arithmetic operations (e.g., addition, subtraction), the algorithm starts by invoking an ALU operation on the operands' LS fragments, thereby producing both a LS partial and a carry out bit. The algorithm writes the partial to designated storage, whereas the processor's state machine typically stores the carry out bit to an ALU status register.

  7. Standard step method - Wikipedia

    en.wikipedia.org/wiki/Standard_Step_Method

    Note the location of critical flow, subcritical flow, and supercritical flow. The energy equation used for open channel flow computations is a simplification of the Bernoulli Equation (See Bernoulli Principle), which takes into account pressure head, elevation head, and velocity head. (Note, energy and head are synonymous in Fluid Dynamics.

  8. Curve-shortening flow - Wikipedia

    en.wikipedia.org/wiki/Curve-shortening_flow

    A flow is a process in which the points of a space continuously change their locations or properties over time. More specifically, in a one-dimensional geometric flow such as the curve-shortening flow, the points undergoing the flow belong to a curve, and what changes is the shape of the curve, its embedding into the Euclidean plane determined by the locations of each of its points.

  9. Mask (computing) - Wikipedia

    en.wikipedia.org/wiki/Mask_(computing)

    In computer science, a mask or bitmask is data that is used for bitwise operations, particularly in a bit field.Using a mask, multiple bits in a byte, nibble, word, etc. can be set either on or off, or inverted from on to off (or vice versa) in a single bitwise operation.
