Study Notes
Understanding Pipelining and Superscalar Architectures
- Sequential execution ensures no instruction starts until the previous is completed
- Pipeline execution allows partial overlapping of instruction execution
- Superscalar architecture involves multiple pipelines or a single pipeline with multiple execution units
- A pipeline processor comprises a sequence of data processing circuits called stages
- In an ideal pipeline, each stage completes its operation in one clock cycle
- Examples of processors using pipeline include Intel 80486 CPU with a single five-stage pipeline and Pentium 4 with a single 20-stage pipeline
- Pipeline setup time is the time needed for the pipeline to become full
- Latency time is the time needed by the CPU to finish executing a single instruction
- CPU throughput is the maximum number of instructions completed in one second
- Constraints on instruction level parallel processing include data dependency and resource conflict
- Data dependency occurs when one instruction depends on the result of a previous instruction
- Resource conflict arises when there is competition for the same resource at the same time
