Unit 4 – Q & A



1. Explain instruction level parallelism and its difficulties in implementing it?
Instruction-level parallelism (ILP) is a measure of how many of the operations in a computer program can be performed simultaneously. The potential overlap among
instructions is called instruction level parallelism.


ILP is to Achieve not only instruction overlap, but the actual execution of more than one instruction at a time through dynamic scheduling and how to maximize the throughput of a processor. For typical RISC processors, instructions usually depend on each other too and as a result the amount of overlap is limited.
Instruction level dependencies and hazards during ILP
If two instructions are not dependent, then they can execute simultaneously— assuming sufficient resources that is no structural hazards. if one instruction depends on another, they must execute in order though they may still partially overlap.
  1. Data dependencies


Data dependence means that one instruction is dependent on another if there exists a chain of dependencies between them. . Compilers can be of great help in detecting and scheduling around these sorts of hazards; hardware can only resolve these dependencies with severe limitations.
