| Please note that the content of this book primarily consists of articles
available from Wikipedia or other free sources online. A vector
processor, or array processor, is a central processing unit (CPU) that
implements an instruction set containing instructions that operate on
one-dimensional arrays of data called vectors. This is in contrast to a
scalar processor, whose instructions operate on single data items. The
vast majority of CPUs are scalar. Vector processors first appeared in
the 1970s, and formed the basis of most supercomputers through the 1980s
and into the 1990s. Improvements in scalar processors, particularly
microprocessors, resulted in the decline of traditional vector
processors in supercomputers, and the appearance of vector processing
techniques in mass market CPUs around the early 1990s. |
