Ärende: New Via C7
==================
From: Adam <mmmmm_beer_mmmm_donuts@moes>

Mmmmm looks good....

Tiny, Low power & fast enough for most....

Certainly enough for a home server/media server.

http://www.via.com.tw/en/products/processors/c7/

"Developed from the ground up for low power based on the VIA CoolStream
architecture, and built using IBM's state-of-the-art 90nm SOI manufacturing
process, the highly integrated VIA C7 processor delivers the greatest x86
performance per watt in the business, capable of running up to 2.0GHz with
ultra low power consumption of around 20W peak power and as low as 100mW (0.1W)
idle power.

Operating at an average power of less than 1W, the VIA C7 processor is the
embodiment of cool processing and sets the standards for next generation of
desktop, mobile and personal electronics systems."


Cryptography on chip....tiny size (30mm2)

"In addition to the world's best random number generator (RNG) and AES
Encryption Engine in the previous processor generation, the VIA C7 processor
adds SHA-1 and SHA-256 hashing for secure message digests, and a hardware based
Montgomery Multiplier supporting key sizes up to 32K in length to accelerate
public key cryptography, such as RSAÖ. The VIA C7 also provides execute
protection (NX), providing protection from malicious software such as worms and
viruses, and is used in MicrosoftR WindowsR XP with SP2. Integrating security
directly onto the processor die ensures speeds and efficiency many times that
available in software, yet with negligible impact on processor performance. VIA

"

I can foresee many many uses for this wee beastie.
