Intel articles about low-power CPU states

Anshul writes with two relevant links for low power states in CPUs:

2006 article about P and C states in Intel processors.

The second article talks about the C1E (extended HLT) state, (Page 6) which is like normal C1 but also turns voltage down to the lowest level. This type of sleep state may address some of the issues of using idle states in the first two papers we read this semester.

    If the 2nd link doesn't work, try removing the extra space that creeped into the link.

    Thanks - I've removed the creeping space.
