Shift register lookup table. A shift register lookup table, also shift register LUT or SRL, refers to a component in digital circuitry. It is essentially a shift register of variable length. The length of SRL is set by driving address pins high or low and can be changed dynamically, if necessary. [1]
For a trivial hash function lookup, the unsigned raw data value is used directly as an index to a one-dimensional table to extract a result. For small ranges, this can be amongst the fastest lookup, even exceeding binary search speed with zero branches and executing in constant time. [6]
Alt+⇧ Shift, Ctrl+⇧ Shift, ⊞ Win+Space, ⊞ Win+⇧ Shift+Space. Alt+⇧ Shift changes between languages while Ctrl+⇧ Shift changes between keyboard layouts of the same language. The latter two display a menu with the currently selected input method highlighted, and debuted in Windows 8. ⊞ Win+⇧ Shift+Space goes
Uniform binary search is an optimization of the classic binary search algorithm invented by Donald Knuth and given in Knuth's The Art of Computer Programming.It uses a lookup table to update a single array index, rather than taking the midpoint of an upper and a lower bound on each iteration; therefore, it is optimized for architectures (such as Knuth's MIX) on which
One method of copying an object is the shallow copy.In that case a new object B is created, and the fields values of A are copied over to B. [3] [4] [5] This is also known as a field-by-field copy, [6] [7] [8] field-for-field copy, or field copy. [9]
For example, in most keyboard layouts the Shift key combination ⇧ Shift+A will produce a capital letter "A" instead of the default lower-case letter "a" (unless in Caps Lock or Shift lock mode). A combination of Alt + F4 in Microsoft Windows will trigger the shortcut for closing the active window ; in this instance, Alt is the modifier key.
A foreign key is a set of attributes in a table that refers to the primary key of another table, linking these two tables. In the context of relational databases, a foreign key is subject to an inclusion dependency constraint that the tuples consisting of the foreign key attributes in one relation, R, must also exist in some other (not necessarily distinct) relation, S; furthermore that those ...
Pressing either Shift key when the screen is blank or the computer is asleep will wake the computer. [citation needed] On some keyboards, if both Shift keys are held down simultaneously only some letters can be typed. For example, on the Dell keyboard Model RT7D20 only 16 letters can be typed. This phenomenon is known as "masking" and is a ...
