1. Tomasulo’s Algorithm
X=Y+Z and A=B*C
4 Registers

3. Arithmetic pipeline design
Fixed point operations
Floating point operations

4. Static arithmetic pipelines
Arithmetic pipeline stages

5. Multiply pipeline design

6. Multifunctional Arithmetic Pipeline
Static arithmetic pipelines are designed to perform a fixed function and thus called unifunctional. When a pipeline can perform more than one function, it is called multifunctional.
A multifunctional pipeline can be either static or dynamic. Static pipelines perform one function at a time, but different function can be performed at different times.
A dynamic pipeline allows a several functions to be performed simultaneously through the pipeline as long as there are no conflicts in the shared usage of pipeline stages.

9. Superscalar pipeline design
Pipeline structure.
Data dependences.
Pipeline stalling: lowers pipeline utilization.
