Nov 01 04:19:38 <[g2]> lennert you BIG DOG!
Nov 01 04:19:47 <lennert> what? :)
Nov 01 04:20:18 <[g2]> "my virtex 2 pro board is shipping" :)
Nov 01 04:20:22 <lennert> yeah
Nov 01 04:20:26 <lennert> hope it'll be here soon
Nov 01 04:20:30 <[g2]> that's nice
Nov 01 04:20:36 <[g2]> congrats
Nov 01 04:20:39 <lennert> thanks!
Nov 01 04:20:44 <lennert> i've got quite some stuff to try out with it
Nov 01 04:21:05 <[g2]> they've got the onboad ppcs
Nov 01 04:21:12 <[g2]> hardcores
Nov 01 04:21:15 <lennert> a guy here wants me to do his neural nets in an fpga
Nov 01 04:21:20 <lennert> yeah
Nov 01 04:21:39 <lennert> what i'd love to do is to get the sata and dram running, and then just run linux on it
Nov 01 04:22:17 <[g2]> that shouldn't be too hard
Nov 01 04:38:59 <vmaster> you guys are mainly interested in an XScale debugger, right? not so much ARM7/ARM9?
Nov 01 04:39:21 <lennert> vmaster: xscale for me
Nov 01 04:45:35 <vmaster> guess i'll add that next - arm7/arm9 is almost done
Nov 01 06:24:04 <ep1220> prpplague: To answer yesterdays question: Yes there is more tested
Nov 01 06:24:11 <prpplague> ep1220: ahh lovely
Nov 01 06:24:18 <ep1220> It works the same as my first prototype
Nov 01 06:24:27 <prpplague> ep1220: cool
Nov 01 06:24:44 <prpplague> ep1220: when ya gonna post schematics and gerbers?
Nov 01 06:25:02 <ep1220> not yet tested is the feature: "take Levelshifter supply Voltage from target"
Nov 01 19:02:03 <lennert> whee, i'm running DES in a spartan3
Nov 01 19:03:11 <lennert> Clock period: 5.480ns (frequency: 182.472MHz)
Nov 01 19:03:21 * lennert suspects that's a little on the high side
Nov 01 19:05:30 <[g2]> cool
Nov 01 19:05:47 <[g2]> congrats
Nov 01 19:06:08 <[g2]> so 182.5 ish cracks per second eh ?
Nov 01 19:06:14 <[g2]> per spartan3
Nov 01 19:06:38 <lennert> well
Nov 01 19:06:41 <lennert> i suspect the number is on the high side
Nov 01 19:06:46 <[g2]> or about 61 triple DES
Nov 01 19:06:47 <lennert> but maybe
Nov 01 19:07:09 <lennert> 2^56 / 182472000 = 394896718.6
Nov 01 19:07:12 <[g2]> with M after the numbers :)
Nov 01 19:07:30 <lennert> a thousand spartan3s, it'll take 100 hours
Nov 01 19:07:39 <lennert> to exhaust 2^56
Nov 01 19:07:50 <[g2]> or 50 hours on average :)
Nov 01 19:07:55 <lennert> yeah
Nov 01 19:08:01 <[g2]> less than a weeken
Nov 01 19:08:02 <[g2]> d
Nov 01 19:08:06 <lennert> yeah, not bad
Nov 01 19:08:18 <lennert> ~$30 per spartan3 though :)
Nov 01 19:08:33 <lennert> still, $40k is not much for a machine that can crack des in a weekend
Nov 01 19:08:59 <[g2]> to me maybe but not to other bigger entities
Nov 01 19:09:23 <lennert> i mean, if your goal is to crack des in a weekend, it's likely that you'll have the $40k to shell out for it
Nov 01 19:09:25 <[g2]> that's like a whole development budget +
Nov 01 19:09:49 * [g2] has "Loftier" goals :)
Nov 01 19:10:03 <lennert> hehe
Nov 01 19:10:10 <[g2]> but it is a cool benchmard
Nov 01 19:10:11 <[g2]> k
Nov 01 19:10:18 <lennert> i don't even know if i have enough area to run multiple DES cores in parallel
Nov 01 19:10:31 <lennert> i definitely want to try this on the virtex2 pro board
Nov 01 19:10:49 <lennert> how many des cores i'd be able to run on that.. ?
Nov 01 19:10:59 <[g2]> well the $30-40K number probably changes a lot if you go to multiple engines on chip
Nov 01 19:11:08 <[g2]> like a 1.5 or 5M gate part
Nov 01 19:11:13 <lennert> yeah
Nov 01 19:11:28 <[g2]> so $30-40K might be 6 hours
Nov 01 19:11:33 <[g2]> on average
Nov 01 19:12:04 <ka6sox-office> the NSA has its own FAB plant.
Nov 01 19:12:14 <[g2]> really ?
Nov 01 19:12:22 <lennert> ka6sox-office: the NSA is most likely behind on xilinx
Nov 01 19:12:29 <[g2]> i guess that would make sense
Nov 01 19:12:34 <ka6sox-office> ya
Nov 01 19:12:35 <lennert> ka6sox-office: they're not so cutting edge as many people believe
Nov 01 19:12:43 <[g2]> hey here's a mask can you make some of these ?
Nov 01 19:13:03 <lennert> [g2]: now do it in 65nm :)
Nov 01 19:13:24 <[g2]> they're probably on 500nm :)
Nov 01 19:13:43 <[g2]> but it's hardened and runs from space :)
Nov 01 19:13:48 <lennert> yeah
Nov 01 19:13:55 <lennert> and it's tamper-proof and tempest-proof
Nov 01 19:14:05 <lennert> and every gate has 50 lines of specs dedicated to it
Nov 01 19:14:29 <ka6sox-office> I'm talking about the stuff in the Basement.
Nov 01 19:14:33 <[g2]> and 3 redundant paths
Nov 01 19:14:48 <[g2]> 2 of 3 votes wins
Nov 01 19:15:20 <lennert> triple module redundancy, yes
Nov 01 19:15:25 <ka6sox-office> better than the 5 500kps machines that run the shuttle
Nov 01 19:18:43 <lennert> i'll do an md4 core next
Nov 01 19:19:06 <[g2]> lennert is turning into the vhdl man!
Nov 01 19:19:17 <lennert> [g2]: i'm just messing around
Nov 01 19:22:05 <lennert> anyway, bed time
Nov 01 19:22:06 <lennert> g'nite all
Nov 01 19:23:07 <ka6sox-office> nite Lennert
Nov 01 19:28:27 <[g2]> sweet dreams
Nov 02 00:15:12 <ka6sox-away> ep1220: ping
