The scalar processor is the simplest class of microprocessors . [1] The scalar processor processes one data element per instruction (SISD, Single Instruction Single Data), typical data elements may be integers or floating point numbers . In vector processors (SIMD, Single Instruction Multiple Data), unlike scalar ones, one instruction works with several data elements.

Notes
- ↑ The processor in this case may be a central processor or ALU . In some cases, the processor may consist of a central processor and several ALUs, representing a superscalar processor .
