00:13 <penguin42> huh, they've had OpenCL going on the i.mx6

00:14 <lkcl__> penguin42: yeah! 16GFLOPS, too.

00:14 <penguin42> that ain't bad going I guess

00:14 <lkcl__> for a 1, 1.5 watt processor? mmm... yeah, i'd say so :)

00:15 <penguin42> now how many of those can you squash on a board

00:15 <lkcl__> yeah exactly. well, the GK802 shows us you can get them into a veeery small space

00:16 lkcl__ is now known as lkcl

00:18 <penguin42> hmm those are SP though

00:19 fra79Wii has joined #arm-netbook

00:19 <penguin42> lkcl: Do you have the PCIe from the i.MX6 coming out anywhere?

00:36 bsdfox has joined #arm-netbook

00:42 <lkcl> penguin42: not a chance. there's quite literally no space for it.

00:43 <penguin42> bah

00:43 <lkcl> i cut power to the PCIe in order to save on components. if you look at sabre_lite_revD.pdf

00:44 <lkcl> you'll see that there's *twenty one* components needed to support the power and signals for PCIe

00:44 <penguin42> ouch

00:45 <lkcl> mostly those are capacitors - 4 on the 1.2v line

00:45 <penguin42> nod

00:45 <lkcl> 4 on the 1.2v VPTX line (whatever that is)

00:45 <lkcl> 4 on the 2.5V

00:46 <lkcl> then there's a 47uF capacitor (those are huge monsters)

00:46 <lkcl> http://hands.com/~lkcl/eoma/iMX6/sabre_lite-revD.pdf - page 3

00:46 <lkcl> ... where would i put the bloody things? :)

00:46 <buZz> wtf, imx6 has a PCIe interface? :OOO

00:47 <lkcl> buZz: yep. i believe it's only x1

00:48 <lkcl> it'd only need a 5-pin connector... but there's no room on the imx6 eoma68 pcb for a 5 pin connector

00:50 hp__ has quit [Ping timeout: 264 seconds]

00:50 <lkcl> penguin42: and... after 2 months of running the auto-router 20 times per day, altering the completion order of over 100 signals by hand to get them all to connect i am *not* adding in another 8 lines :)

00:51 <penguin42> haha ok

00:51 <lkcl> *grin*

00:51 <lkcl> it's like... "enough already!".

00:52 <penguin42> hmm how much do those things cost?

00:52 <buZz> :P

00:52 <buZz> is there a eoma68 breakout already?

00:52 <lkcl> funfunfun - i handed it to someone else, they ran a dual or quad-core pentium system, auto-route completion for them was only 80%.

00:53 <lkcl> buZz: not yet. might have to make one in a hurry though

00:53 <penguin42> a PCI-e card with one of those on would be interesting; gigE, and the fun stuff on the back

00:53 <buZz> boards are more usefull when you can use them ;)

00:53 <lkcl> penguin42: the iMX6 eoma68 board? dunno

00:53 <penguin42> lkcl: No, I meant just an iMX6

00:53 <lkcl> buZz: iknowiknowiknow! the priority's been on the flying squirrel

00:53 <lkcl> penguin42: ohh... 1sec...

00:54 <buZz> :P

00:55 <penguin42> still, that is a nice chip

00:57 <lkcl> www.freescale.com/webapp/sps/site/prod_summary.jsp?code=i.MX6Q&nodeId=018rH3ZrDRB24A&tab=Buy_Parametric_Tab&fromSearch=false

00:57 <lkcl> that's the quad

00:58 <lkcl> $32 and upwards

00:58 <penguin42> yeh a bit much just to sell as a gigE card

00:59 <lkcl> http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=i.MX6D&tab=Buy_Parametric_Tab&nodeId=018rH3ZrDRB24A&fromPage=tax

00:59 <lkcl> that's the dual - $22 and upwards.

01:00 <penguin42> so how much are you reckoning the cards will come in at?

01:00 <penguin42> the EOMA cards that is

01:01 <lkcl> mmm... assuming that the RAM is 1gbyte and everything else is the same, the BOM is going to be around....

01:02 <lkcl> gige +$3

01:02 <lkcl> beefier PMICs... +$3 appx

01:02 <lkcl> dual-core SoC ... $22-7 = +$15 appx

01:02 <lkcl> NAND's the same

01:02 <lkcl> connectors are the same

01:03 <lkcl> PCB's still 6-layer

01:03 * penguin42 waits for the irc spreadsheet moded

01:03 <lkcl> $30+3+3+15 =

01:03 <lkcl> $51 for the BOM, appx.

01:03 <lkcl> so x1.5 or x2 on that

01:03 <lkcl> somewhere around $75

01:04 <penguin42> hmm that's OK

01:04 <lkcl> $100 for 1-offs

01:04 <lkcl> it sort-of all adds up

01:04 <penguin42> yeh

01:05 <lkcl> 's'a big jump though, just to go to dual-core, a cortex a9 and gigabit ethernet.

01:06 <penguin42> right, but it's actually useful

01:06 <lkcl> i'm looking forward to a cortex a7 dual-core and/or 22nm, just to get the power down

01:06 <lkcl> :)

01:06 <penguin42> what's the power?

01:06 <lkcl> power down = less PMIC components

01:06 fra79Wii has quit [Quit: Leaving]

01:07 <penguin42> ah

01:07 <lkcl> a LOT for such a small card. if you push the iMX6 flat-out (3 video decodes) it can ask for something mad like 5 watts

01:07 <lkcl> or 4.5

01:07 <lkcl> that's with 3 video decodes, 100% CPU usage, 1333mhz DDR3 RAM, data in, data out

01:08 <lkcl> there's an app note on it.

01:08 <penguin42> and how much is the type2 card spec'd at handling?

01:08 <lkcl> 10 watts... but that's with a heat-sink and other thermal management

01:09 <penguin42> nod

01:09 <lkcl> it's close to the limit. certainly the quad is over the limit.

01:10 <lkcl> so, we just have to say "ok, you have a thermal limit, and you have power management. if you go over the limit, ramp the clock rate back or it will be ramped back for you"

01:11 <penguin42> yeh

01:11 <lkcl> in production we'll flood the cases with thermal gel. loovely stuff.

01:11 <penguin42> yeuch

01:12 * lkcl must write to wits-tech check on the PCBs

01:13 <SPG> lkcl master adb62a4 rhombus freescale/iMX6.mdwn * add pricing links * http://git.hands.com/?p=rhombus.git;a=commitdiff;h=adb62a4

01:13 <penguin42> lkcl: Have you seen the kind of rubber sheet you can get that's thermal conductive ?

01:15 <SPG> lkcl master 10953d8 rhombus freescale/iMX6.mdwn * add pricing links * http://git.hands.com/?p=rhombus.git;a=commitdiff;h=10953d8

01:16 <lkcl> penguin42: yes. first saw one in a FIC ION PC (AMD Geode LX800 based). lovely

01:20 <penguin42> I suppose I'd better go to bed now that it's all of a sudden got late
