| Fallenou | lekernel: how many LUT does lm32 take in the Spartan 6 ? | 00:41 |
|---|---|---|
| kristianpaul | ~20K was it? i dont remenber well | 00:56 |
| kristianpaul | or 2K.. | 00:56 |
| kristianpaul | he | 00:56 |
| kristianpaul | yes | 01:04 |
| kristianpaul | Fallenou: http://www.ohwr.org/projects/lm32 | 01:04 |
| Fallenou | my first incomplete draft of mips core already takes 2,5 K lut of my lattice fpga | 01:04 |
| kristianpaul | :-/ | 01:04 |
| Fallenou | it's impressive lm32 : 2,5 k LUT, I-cache D-cache 2 way set associative, 1 cycle mult and div and 125 MHz on Cyclone 3 | 01:06 |
| Fallenou | it must be well designed :) | 01:06 |
| kristianpaul | Thanks Lattice EEs ! ;) | 01:07 |
| Fallenou | I will try to do better ! | 01:07 |
| Fallenou | but it won't be easy | 01:07 |
| kristianpaul | Fallenou: when you ordered the laticce board do they told you shipping costs after ? | 01:09 |
| Fallenou | I don't remember :x | 01:10 |
| Fallenou | sorry | 01:10 |
| Fallenou | a friend ordered a few boards actually | 01:10 |
| Fallenou | and I paid him back | 01:10 |
| Fallenou | we had extra fee because of the import | 01:10 |
| kristianpaul | yeah, i'm afraid of that too | 01:10 |
| Fallenou | it cost me 90 EUR in total (shipping included) | 01:11 |
| Fallenou | but we splitted shipping cost in 3 | 01:11 |
| kristianpaul | also than they dont tell me shipping costs AND i already sent they my credit card info in advance :-|, if i were to ther of course | 01:11 |
| Fallenou | we had like $75 in shipping I think | 01:11 |
| kristianpaul | urgh and you live in EEUU ! | 01:12 |
| Fallenou | shipping cost is lower in EU ? | 01:12 |
| kristianpaul | s/EEUU/Europe | 01:12 |
| kristianpaul | dont you? | 01:12 |
| Fallenou | yes I live in EU | 01:13 |
| Fallenou | it cost 297$ for 3 boards + $75 for shipping of those 3 boards together | 01:13 |
| Fallenou | maybe it's expensive because 3 boards are bigger to transport | 01:13 |
| Fallenou | dunno | 01:14 |
| kristianpaul | wpwrak: will like this http://siliconexposed.blogspot.com/2012/01/first-bga-board.html | 03:35 |
| wpwrak | nice ;) | 03:40 |
| wpwrak | lekernel: btw, why are only PNGs shared but JPEGs aren't ? (you record the file name for PNGs only. since you explicitly handle NULL file names, this looks intentional ?) | 06:54 |
| wolfspraul | wpwrak: the idea of adding internal 5*2 headers for USB got me thinking... are there other standard headers on PC mainboards that, if offered on M1, could allow people to plug in existing cheap stuff? | 08:44 |
| wolfspraul | I won't go search now, but it's something I will keep an eye open for. | 08:45 |
| wolfspraul | the header we are discussing now has no protection against reverse insertion. wondering how bad the damage would be if peopel inserted wrong, or how we could steer away from that | 08:49 |
| wolfspraul | I've also found this type of USB connector http://images.bit-tech.net/news_images/2008/10/gigabyte-shows-bit-tech-its-final-x58s/Gigabyte-X58-UD5P.jpg | 08:50 |
| wolfspraul | (bright yellow connector on left side) | 08:50 |
| wolfspraul | that looks like 2*5 but in a smaller pitch, and embedded in this plastic to enforce correction position | 08:50 |

| wpwrak | wolfspraul: the 5x2-1 header does protect against reverse insertion :) and yes, some are shrouded, for additional protection (but also possibly with additional complication) | 10:31 |
| wpwrak | lekernel: ah, you shouldn't have :) i;m planning to switch all this to passing FILE * to the loaders anyway, so that we don't do multiple lookups, risking races | 10:32 |

| wpwrak | hmm, for regression testing of the pfpu itself, it would be nice to be able to run it on a PC. but i guess that's not so easy. (if we want accurate behaviour, e.g., a precise replica of rounding errors) | 11:44 |
| wpwrak | the second best may be to have some way to make the M1 execute a small code fragment, e.g., received form the command line, and send the results back | 11:45 |
| wpwrak | that may be the opportunity for using "expect" ;-)) | 11:47 |
| wpwrak | half a lifetime ago, i think i wrote a scriptable telnet ... wish i remembered if that's still around somewhere. probably not. | 11:49 |
| wpwrak | kewl. found a gcc diagnostics error :) | 13:20 |
