Scalar
(gcide) | Scalar \Sca"lar\, n. (Math.)

but not direction; -- distinguished from a vector, which has
both magnitude and direction.
[1913 Webster] |
scalar
(wn) | scalar
adj 1: of or relating to a musical scale; "he played some basic
scalar patterns on his guitar"
2: of or relating to a directionless magnitude (such as mass or
speed etc.) that is completely specified by its magnitude;
"scalar quantity"
n 1: a variable quantity that cannot be resolved into components |
scalar
(foldoc) | scalar
1. A single number, as opposed to a vector or
matrix of numbers. Thus, for example, "scalar
multiplication" refers to the operation of multiplying one
number (one scalar) by another and is used to contrast this
with "matrix multiplication" etc.
2. In a parallel processor or {vector
processor}, the "scalar processor" handles all the sequential
operations - those which cannot be parallelised or vectorised.
See also superscalar.
3. Any data type that stores a single value
(e.g. a number or Boolean), as opposed to an aggregate
data type that has many elements. A string is regarded as a
scalar in some languages (e.g. Perl) and a vector of
characters in others (e.g. C).

(wn) | scalar field
n 1: a field of scalars |
scalar matrix
(wn) | scalar matrix
n 1: a diagonal matrix in which all of the diagonal elements are
equal |
scalar product
(wn) | scalar product
n 1: a real number (a scalar) that is the product of two vectors

superscalar
(foldoc) | superscalar
A superscalar architecture is a uniprocessor
that can execute two or more scalar operations in parallel.
Some definitions include superpipelined and VLIW
architectures; others do not. Superscalar architectures
(apart from superpipelined architectures) require multiple
functional units, which may or may not be identical to each
other. In some superscalar processors the order of
instruction execution is determined statically (purely at
compile-time), in others it is determined dynamically (partly
at run time).
