2. • It uses two basic concepts
• Parallelism in instruction stream
• Parallelism in data stream
• A CPU has n Program Counter so there are n
Instruction streams
• A data stream can be used as sequence of data
• It has 4 possible combinations
4. Features
• One Job at one time
• SISD corresponds to traditional mono processors
• Single data stream handled by single instruction
• A. Uniprocessor system which generates single stream of
instruction from program
7. Features
•Single CU multiple Processing unit
•All processing units are synchronised
•Instructions on different sets on data
•CU fetches instruction from memory and distributes
into multiple Processing units
13. Features
•It is true Multiprocessor
•In contrast to SIMD, MIMD is general purpose machine
•When all cores/processer run one program it's called
SPMD(single program multi data)
•Usually every processor has own data to execute
