Answer 1

1. Superscalar :

Technique that enables the processor to execute more than one instruction per clock cycle by selcecting them during execution

2. Dynamic pipeline scheduling :

Hardware support for reordering instruction execution so as to avoid stalls

3. Commit unit :

The unit that decides when it isafe to release the result of an operation to programmer visible registers and memory.

4. Reservation station :

buffer within a functional unit that holds the operands and operation

5. Reordering buffer :

buffer that holds the results until it is safe to store the results to a memory or register.
