BACKGROUND
Two parameters: Instruction stream, Data stream.
SISD (Single Instruction stream - Single Data stream)
SIMD (Single Instruction stream - Multiple Data stream)
- several processors execute the same instruction on different data.
MISD (Multiple Instruction stream - Single Data stream)
- many processors execute the different instructions on the same data. (not practical !)
MIMD (Multiple Instruction stream - Multiple Data stream)
- several processors execute different instructions on different data.
