- Can somebody provide me with comments or references to pros and cons of
- having a large register set on-chip. Lets say 64 Int and 64 FP registers be it
- 32-bit or 64-bit.
- Specifically is there a study that shows how many registers typical
- programs would like to have (i.e. unlimited registers as resources, like
- the studies on unlimited number of execution units)?
- This is for a microprocessor.
