I think we should put in additional effort to satisify their needs. 11:44 < gmaxwell> Their hardware is a 64k ram, 256k flash cortex m4. Current signing table size is a bit burdensome considering. 11:45 < gmaxwell> They tendered a patch that havles it, but with a big speed hit. 11:46 < gmaxwell> An alternative would be to switch it to use the fixed window NAF, which would halve the table size at ~the same speed (maybe make it faster? have we tried?). 11:49 < gmaxwell> Sounds like they'd also like verify and the big G precomp table is out for that. They suggested running ecmultconst twice, I measure a ~2.4x slowdown in verify for that. But using ecmult_const + ecmult_gen is only a 1.9x slowdown. so probably a better tradeoff assuming a 32kb gen table is okay. 13:22 -!- evoskuil [~evoskuil@c-73-225-134-208.hsd1.wa.comcast.net] has quit [Ping timeout: 260 seconds] 13:31 -!- evoskuil [~evoskuil@c-73-225-134-208.hsd1.wa.comcast.net] has joined #secp256k1 18:32 -!- maaku [~quassel@botbot.xen.prgmr.com] has quit [Read error: Connection reset by peer] 18:36 -!- maaku [~quassel@botbot.xen.prgmr.com] has joined #secp256k1 18:37 -!- maaku is now known as Guest57960 18:45 -!- Guest57960 is now known as maaku 20:01 -!- maaku [~quassel@botbot.xen.prgmr.com] has quit [Remote host closed the connection] 20:02 -!- maaku [~quassel@botbot.xen.prgmr.com] has joined #secp256k1 20:02 -!- maaku is now known as Guest67646 20:13 -!- Guest67646 is now known as maaku 20:36 < gmaxwell> andytoshi: unconsidered benefits of lowS-- gmp based scalar inverse is 3.5% faster for lowS instead of highS. 20:41 < gmaxwell> hm. or maybe thats measurement error. :P
