| Fallenou | thanks | 08:11 |

| GitHub151 | milkymist/master 711b989 Larry Doolittle: pfpu/test: keep up with pipeline length changes | 08:14 |
| lekernel | pots are working :) | 11:38 |
| Fallenou | pots? | 11:55 |
| Fallenou | the slider? | 11:55 |
| lekernel_ | slider and blackout, yes | 13:25 |
| Fallenou | lekernel_: (slider) yeah! a real working mixer now :) | 13:43 |
| Fallenou | what's the blackout? | 13:43 |
| Fallenou | a switch to turn off one input? | 13:43 |
| lekernel_ | "intensity" of the output | 13:43 |
| lekernel_ | black when at min, no change when at max | 13:43 |
| GitHub158 | [milkymist-ng] sbourdeauducq pushed 2 new commits to master: http://git.io/zVHAyA | 13:47 |
| GitHub158 | milkymist-ng/master 32c478a Sebastien Bourdeauducq: top: integrate ADC for pots | 13:47 |
| GitHub158 | milkymist-ng/master 9f81afb Sebastien Bourdeauducq: software/videomixer: connect crossfade and blackout pots | 13:47 |
| lekernel | any idea about what precisely can cause DVI signal errors when the SDRAM is read? | 14:13 |
| lekernel | tried rewiring the DVI clock to a GCLK pin (with coax and to the SD card pin, so quite shielded from the SDRAM traces) - no change | 14:14 |
| GitHub34 | [milkymist-ng] sbourdeauducq pushed 1 new commit to master: http://git.io/NSWy8g | 15:20 |
| GitHub34 | milkymist-ng/master 581cf5b Sebastien Bourdeauducq: timer: atomic reads | 15:20 |
| lekernel | hmm, vivado in command line looks usable | 16:00 |
| lekernel | it's actually much faster than ISE | 16:03 |
| wpwrak | didn't someone (lars ?) mention some horrible slowdown ? | 16:06 |
| lekernel | I did, but this was with the GUI | 16:08 |
| lekernel | and an older version | 16:08 |
| wpwrak | oh, a speed penalty for gui users. nice :) | 16:10 |
| lekernel | it does synthesis + p&r of the whole lm32 core under a minute | 16:11 |
| wpwrak | how long did it take on your system before ? | 16:11 |
| lekernel | https://gist.github.com/sbourdeauducq/5569498 | 16:12 |
| lekernel | not sure about the exact figure... but I remember waiting ages | 16:15 |
| kristianpaul | does vivado still using the xilinx description language or they wrote a new one? | 17:02 |
| lekernel | XDL? I don't think so... | 17:09 |
| lekernel | but not sure | 17:09 |
| lekernel | try :) | 17:09 |
| kristianpaul | oh, 104usd for a zynq soc (XC7Z010) | 17:11 |
| larsc | yea pretty expensive :/ | 17:13 |
| kristianpaul | indeed | 17:13 |
| larsc | which is funny that the paralella sells for 99$ and has a zynq on the board | 17:14 |
| davidc__ | For those that don't know - digikey prices for Xilinx stuff bear no relation to actual real-world volume prices | 17:29 |
| wpwrak | davidc__: is there a conversion function ? | 17:30 |
| wpwrak | or a collection of data points ? | 17:31 |
| davidc__ | wpwrak: nah; just call up Avnet/$YOUR_DISTY, ask for pricing at $Xkunits, call em back a week later saying that you think you're going with Altera and ask if they can do any better | 17:32 |
| davidc__ | "Its a really nice part and we like developing with ISE (*snort*), but the pricing just doesn't work for our design" | 17:33 |
| wpwrak | dirty :) | 17:34 |
| davidc__ | wpwrak: I've see GigE switch silicon go from $35 /pc down to $7.25/pc | 17:35 |
| davidc__ | Just by making two chipmakers duke it out with each other. [I'd rather have given them bricks and shut them in a closet, but the purchasing guy overruled me] | 17:36 |
| davidc__ | wpwrak: keep in mind though that if you don't actually buy $X kunits, they're not going to give you good pricing the next time round | 17:37 |
| davidc__ | so use actual real volume estimates | 17:37 |
| wpwrak | davidc__: perhaps we need a "priceleaks" where people can anonymously post chips, quantity, and price. randomize and filter the data a little to make it harder to trace it back to a specific customer | 18:03 |
| davidc__ | Meh, but good luck getting the distys/mfgs to give you those prices. Besides, if you really want to get depressed about chip prices; get a native speaker in China to get quotes from legit distys for the same parts | 18:07 |
| larsc | hehe | 18:11 |
| wpwrak | ;-) | 18:17 |
