VIA details a secure, efficient C5J "Esther"
May 21, 2004

VIA has released details of their forthcoming C5J "Esther" processor core. Building on the success of the Nehemiah's PadLock Hardware Security Suite, "Esther" adds execution (NX) protection and support for more encryption standards - Montgomery Multiplier support for RSA encryption, and secure Hash algorithms in both SHA-1 and SHA-256 flavours. NX keeps malicious code from spreading in the computer's memory - look out for NX support in the upcoming Windows Service Pack 2.

Esther is lean too. Power consumption is an amazing 3.5W at 1 GHz. Other features: support for an 800 Mhz Front Side Bus, and a larger L2 cache.

Ultimately, VIA claims the new architecture will handle processor speeds of 2GHz and above. Esther was designed by VIA subsiduary Centaur Technology, and will be manufactured by IBM at their 300mm (12 inch) foundry in East Fishkill, New York.
