performance

Performance, power and complexity
Complexity is not proportional to area
Data flow is responsible for most of the area, control circuits which
typically take very little area are responsible for most of the complexity
Arrays take significant area but logically are very simple
Complexity is not proportional to power
Data flow with lots of activity is responsible for most of the power
Arrays and register files are logically simple, but are a significant
power component
Control circuits that take care of corner cases show very little switching
activity but are the most challenging in terms of complexity
Hardware for the handling of memory coherence, translation, MP
