Study Notes

Instruction-Level Parallelism (ILP)

ILP is a measure of how many operations a computer program can be performed simultaneously.

Approaches to ILP

Dynamic parallelism: works on dynamic parallelism, where the parallelism is determined at runtime.
Static parallelism: works on static parallelism, where the parallelism is determined at compile time.

Processors

Dynamic sequence of parallel execution: processor works on a dynamic sequence of parallel execution.
Static level parallelism: processor works on static level parallelism.

ILP Calculation

If each operation can be completed in one unit of time, three instructions with no dependencies require 1 unit of time to complete.
If three instructions can be completed in a total of two units of time, the ILP of the program is 1.5.
If four instructions can be completed in a total of three units of time, the ILP of the program is 1.33.

The potential overlap among instructions is called instruction-level parallelism.
Static parallelism approach works on static parallelism.
