Array processing
Array processing is signal processing of the outputs of an
array of
sensors to:Enhance the signal-to-interference-plus-noise ratio (SINR) compared to that of a single
sensor using conventional or adaptive
beamforming.Determine the number of emitting sources, the locations of these sources, their
waveforms, and other signal parameters.Track multiple moving sources.

Vector processor
A vector processor, or array processor, is a
CPU design that is able to run mathematical operations on multiple data elements simultaneously. This is in contrast to a
scalar processor which handles one element at a time. The vast majority of CPUs are scalar (or close to it). Vector processors were common in the
scientific computing area, where they formed the basis of most
supercomputers through the 1980s and into the 1990s, but general increases in performance and processor design saw the near disappearance of the vector processor as a general-purpose CPU.

array processor
A
processor capable of executing instructions in which the operands may be arrays rather than
data elements. Synonym vector processor .
array processor
<
processor> (Or "vector processor") A
computer, or extension to its
arithmetic unit, that is capable of performing simultaneous computations on elements of an
array or table of data in some number of dimensions.
The
IBM AltiVec (the "Velocity Engine" used in the
Apple G4 computers) is a vector processor.
Common uses for array processors include analysis of fluid dynamics and rotation of
3d objects, as well as data retrieval, in which elements of a
database are scanned simultaneously. Array processors are very rare now (1998).
