Scalar processor

Scalar processor

Scalar processors represent the simplest class of computer processors.ref|cpu-or-alu A scalar processor processes one data item at a time (typical data items being integers or floating point numbers). In a vector processor, by contrast, a single instruction operates simultaneously on multiple data items. The difference is analogous to the difference between scalar and vector arithmetic.

Notes

# The processors in question may be complete central processing units (CPUs) or separate arithmetic-logic units (ALUs). In some cases, a processor may be made up of one CPU and several ALUs, the combination forming a superscalar processor.
