  2. Multiply–accumulate operation - Wikipedia

    en.wikipedia.org/wiki/Multiply–accumulate...

    Combinational multipliers require a large amount of logic, but can compute a product much more quickly than the method of shifting and adding typical of earlier computers. Percy Ludgate was the first to conceive a MAC in his Analytical Machine of 1909, [ 1 ] and the first to exploit a MAC for division (using multiplication seeded by reciprocal ...

  3. Dice notation - Wikipedia

    en.wikipedia.org/wiki/Dice_notation

    In some games, the above notation is expanded to allow for a multiplier, as in AdX×C or C×dX, where: "×" denotes multiplication, and can be replaced by "/" or "÷" for division. C is a natural number (1 if omitted). For example, 1d6×5 or 5×d6 means "roll one 6-sided die, and multiply the result by 5."

  4. Port multiplier - Wikipedia

    en.wikipedia.org/wiki/Port_multiplier

    A Serial ATA port multiplier is a unilateral splitting device. While it allows one equipped port to connect up to 15 disks, the bandwidth available is limited to the bandwidth of the link to the controller, as of 2012 1.5, 3, or 6 Gbit/s. [3]

  5. Quetzalcoatlus - Wikipedia

    en.wikipedia.org/wiki/Quetzalcoatlus

    Quetzalcoatlus (/ k ɛ t s əl k oʊ ˈ æ t l ə s /) is a genus of azhdarchid pterosaur that lived during the Maastrichtian age of the Late Cretaceous in North America. The type specimen, recovered in 1971 from the Javelina Formation of Texas, United States, consists of several wing fragments and was described as Quetzalcoatlus northropi in 1975 by Douglas Lawson.

    en.wikipedia.org/wiki/Giganotosaurus

    Giganotosaurus (/ ˌ ɡ ɪ ɡ ə ˌ n oʊ t ə ˈ s ɔː r ə s / GIG-ə-NOH-tə-SOR-əs [2]) is a genus of large theropod dinosaur that lived in what is now Argentina, during the early Cenomanian age of the Late Cretaceous period, approximately 99.6 to 95 million years ago.

  7. Torque multiplier - Wikipedia

    en.wikipedia.org/wiki/Torque_multiplier

    A torque multiplier allows the user to generate high torque output without the use of an air compressor or impact gun. A torque multiplier is generally used when there are space limitations that disallow the use of long handles. They are also used as a safer alternative to a cheater bar as lever length and operator effort are both reduced.

  8. Montgomery modular multiplication - Wikipedia

    en.wikipedia.org/wiki/Montgomery_modular...

    The constants R mod N and R 3 mod N can be generated as REDC(R 2 mod N) and as REDC((R 2 mod N)(R 2 mod N)). The fundamental operation is to compute REDC of a product. When standalone REDC is needed, it can be computed as REDC of a product with 1 mod N. The only place where a direct reduction modulo N is necessary is in the precomputation of R ...
