some time ago i was looking for a CPU miner and there were a pair of  miners using special instructions on it.

now,there is no miner using similar technics, and i want to ask:

- why are these int deprecated?
- how could it being ignored, even when thats help reducing CPU overload?
- on ARM architecture, why this cannot be optimized to use these hash capabilities?
-isn't it more power efficient?

CPU mining is dead. Even the biggest, baddest $1000 CPU's may only be able to crank out 30 mhash/sec while consuming on the order of 200 watts of power. Don't bother. By comparisons, you can get a retail Radeon 6450, a very slow, low end GPU for about 30 bucks and it will also do about 30 mhash/sec at a tiny fraction of power, probably in the area of 15 watts. You can also find a Radeon 5970, a very high end dual GPU card for about $250 and it will do 700 mhash/sec with about 200 watts of energy.

Do not bother with CPU mining.
I was thinking more of the special crypto-engines on a pool. even if you think is dead, they were made for this task and are more power efficient. There are two order of magnitud more armv7 proccessors than gpgpu cards and is probably they improves on it  of because security needs.
