An interesting thread to follow on cryptography@ ... -------- Original Message -------- Subject: 5x speedup for AES using SSE5? Date: Sat, 23 Aug 2008 14:00:44 +0100 From: Paul Crowley <p...@ciphergoth.org> To: cryptography at metzdowd.com
http://www.ddj.com/hpc-high-performance-computing/201803067 In the above Dr Dobb's article from a little over a year ago, AMD Senior Fellow Leendert vanDoorn states "the Advanced Encryption Standard (AES) algorithm gets a factor of 5 performance improvement by using the new SSE5 extension". However, glancing through the SSE5 specification, I can't see at all how such a dramatic speedup might be achieved. Does anyone know any more, or can anyone see more than I can in the spec? http://developer.amd.com/cpu/SSE5/Pages/default.aspx -- __ \/ o\ Paul Crowley /\__/ www.ciphergoth.org --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to majordomo at metzdowd.com -- Darren J Moffat
