The incorrect match (when n > 1) is
The incorrect match (when n > 1) is Correct Answer MIMD Model of computer : n control units and 1 ALU
Concept:
SISD:
- SISD stands for single instruction, single data
- SISD is a uniprocessor machine capable of executing a single instruction, which operates on a single data stream.
- Von Neumann computer architecture is SISD
SIMD:
- SIMD stands for Single Instruction, Multiple data
- A single operation executes simultaneously on multiple elements of data.
MIMD:
- MIMD stands for multiple instructions, multiple data
- Separate instruction streams, each with its own flow of control, operate on separate data.
MISD:
- MISD stands for multiple instructions, single data
- In MISD many functional units perform different operations on the same data.
Analysis:
SISD Model of computer: 1 control unit and 1 ALU (Correct)
SIMD Model of computer: 1 control unit and n ALUs (Correct)
MISD Model of computer: n control units and n ALUs (Correct)
MIMD Model of computer: n control units and 1 ALU (Incorrect) because it requires n-control units and n-ALUs.
