Study Notes
Processor Organizations
- SISD (Single Instruction, Single Data): Executes one instruction at a time, using only one set of operands.
- SIMD (Single Instruction, Multiple Data): All processing units execute the same instruction issued by the control unit at any given clock cycle.
- MIMD (Multiple Instruction, Multiple Data): Feeds a single data stream into multiple processing units, which operate on the data independently via independent instruction streams.
Characteristics and Applications
- SISD: Best suited for general-purpose computing, characterized by executing one instruction at a time.
- SIMD: Best suited for specialized problems with high regularity, such as image processing and vector computation.
- MIMD: Best suited for applications requiring massive parallel processing, such as scientific simulations and data processing.
Flynn's Classification
- Two independent dimensions: Instruction stream and Data stream.
- Instruction stream: A sequence of instructions executed by a processor.
- Data stream: A sequence of data being processed by a processor.
- Possible states for each dimension: Two (Single or Multiple).
- Flynn's Classification depends on: The number of instruction streams and data streams in a processor organization.
