1999 Paper 7 Question 3
Comparative Architectures
Why might a processor supporting “dynamic execution” (out-of-order execution
with speculation) yield better performance than a statically-scheduled processor
with a similar number of execution units? [5 marks]
Outline the operation of a dynamic execution processor. You should address the
following issues in your answer:
• register re-use (name dependencies)
• arithmetic exceptions
• control-flow misprediction
• load/store ordering preservation
[10 marks]
What factors are likely to affect the amount of instruction-level parallelism that
will be exploited by future processors? [5 marks]
