| * mafm dislikes pages like OpenPiton's | 05:56 | |
| mafm | but they are everywhere now | 05:56 |
|---|---|---|
| ZipCPU | mafm:What's wrong with OpenPiton's page? | 09:44 |
| mafm | ZipCPU: I don't like the general style of these newfangled pages! now get off my lawn, etc :P :D | 10:16 |
| kc5tja | The fact that you have to scroll on a 1600-pixel tall display is pretty damn loathesome. | 10:57 |
| kc5tja | Just to see the slightest bit of information about the project. | 10:57 |
| kc5tja | That color scheme is pretty garish too. | 10:58 |
| kc5tja | Reminds me vaguely of AmigaOS 1.2, with its blue background and nightmare-inducing-orange color for highlights. | 10:59 |
| kc5tja | What really burns me up are the webpages that have parallax scrolling. | 11:02 |
| kc5tja | I suffer from vertigo, and those pages are very disorienting to me. | 11:03 |
| kc5tja | (at least if the effect is very pronounced.) | 11:03 |
| ZipCPU | Well ... I'm making progress. I discovered that I hadn't turned the DLL on. Now that the DLL is on, the bits are making more sense. | 14:37 |
| ZipCPU | Still, if I write a bunch of ones, they turn into zeros over time. I wonder if that's a refresh bug? | 14:37 |
| ZipCPU | (Working with a DDR3 SDRAM ...) | 14:38 |
| kc5tja | ^--- That, THAT, right there, is why I opted to not go with SDRAM as my first-generation online memory system for the Kestrel. Because I knew stuff like this would inevitably happen. ;) | 15:53 |
| ZipCPU | kc5tja: If you're not failing, you are not trying hard enough. :P | 15:53 |
| kc5tja | Oh believe me, I'm EPICALLY failing right now, even w/out the SDRAM complexity. :D | 15:54 |
| kc5tja | So far, I have instruction decode for OP-IMM and OP-IMM-32 instructions working. Still haven't had the time to implement LOAD or STORE instruction classes yet. :( | 15:55 |
| -!- sandeepkr is now known as X7R | 15:57 | |
| ZipCPU|Laptop | Well, that's a good start .... | 15:58 |
| kc5tja | I get these days of extreme productivity, and then week-long spans of procrastination. | 16:01 |
| -!- X7R is now known as sandeep | 16:21 | |
| -!- sandeep is now known as sandeepkr | 16:21 | |
| Finde | kc5tja: I feel the same about the page | 16:57 |
| Finde | unfortunately as I wasn't willing to make a page myself, I just have to put up with it | 16:57 |
| kc5tja | Page? | 17:05 |
| mafm | Finde: are you from that project? didn't mean to offend :D | 17:06 |
| mafm | this kind of design seems to be popular in many places, e.g. the Jolla phone company | 17:07 |
| kc5tja | I'm so confused. Which project? | 17:07 |
| mafm | kc5tja: I am guessing that the openpiton page that we were talking about before, but maybe I am wrong | 17:08 |
| olofk | Could someone give me a name for a cheap USB JTAG adapter? | 17:08 |
| kc5tja | mafm: Ahh, about the website design. Well, better to have actual silicon working than a nice pretty website without any content at all. | 17:09 |
| olofk | Don't underestimate the power of a nice website. The complete mess of the different sites traditionally used for OpenRISC have turned away more than a few poeple who thought it was just something old and forgotten | 17:16 |
| * kc5tja nods | 17:17 | |
| kc5tja | That's the single biggest fear I have with the Kestrel websites. | 17:17 |
| kc5tja | The Kestrel site is pretty austere and monochrome, which is nice for having a fast-loading page. | 17:18 |
| kc5tja | But, it's not at all "professional." Very HTML 1.0. | 17:18 |
| olofk | kc5tja: I must say that Kestrel has better web resources than most projects I have seen | 17:18 |
| olofk | kc5tja: Have you for example seen the FuseSoC homepage? | 17:22 |
| ZipCPU | olofk: Is there a FuseSoC homepage? | 17:28 |
| olofk | ZipCPU: Nope. That was my point :) | 17:29 |
| ZipCPU | olofk: Point made. | 17:30 |
| olofk | I did buy fusesoc.net several years ago though. Just haven't taken the time to put up something | 17:30 |
| olofk | Thinking of just publishing my poster from the RISC-V workshop there since it probably contains more info than any other source | 17:30 |
| Finde | haha mafm yeah I'm the lead author on the ASPLOS paper about the chip | 17:47 |
| Finde | I mean the platform | 17:47 |
| Finde | but yeah I agree about the site | 17:47 |
| mafm | Finde: so it's ready to tape out, according to the site? | 17:57 |
| Finde | we have silicon in the lab | 17:57 |
| Finde | Mike's giving a talk at hotchips at the end of the month | 17:57 |
| Finde | see day 2: http://www.hotchips.org/program/ | 17:58 |
| Finde | 2:15pm | 17:58 |
| Finde | the videos usually get uploaded after too | 17:58 |
| mafm | Finde: will the lab tape out / sell commercially, or a spin-off, or no reals plans yet? | 17:59 |
| mafm | (btw, it's a sparc32 or a sparc64? Debian removed the former) | 17:59 |
| Finde | we're happy to share with collaborators but we're not planning on selling it as a product | 17:59 |
| Finde | sparc64 | 17:59 |
| mafm | ah, nice :) | 18:00 |
| Finde | unfortunately a 6x6mm chip in IBM 32nm is a bit expensive | 18:00 |
| Finde | it's mainly a way of testing out some research ideas we had | 18:00 |
| mafm | I always wondered why people didn't try to do anything with opensparc... I blamed it on Oracle/Ellison | 18:00 |
| mafm | :P | 18:00 |
| Finde | hence us then releasing openpiton for other researchers to use | 18:00 |
| Finde | haha | 18:00 |
| Finde | yeah me too | 18:00 |
| mafm | Finde: I'm totally oblivious to the perils of fabrication processes and so on, but do you think that it would possible/easy to have it in low volumes as cpu-card in https://www.crowdsupply.com/eoma68/micro-desktop ? | 18:03 |
| mafm | or it's only possible with some arm chips because the fabrication plans already have the chips? | 18:04 |
| ssvb | mafm: I think the RISC-V people were talking about something like $30K per test batch, I guess one may expect a few failed attempts before something useful is produced, but this does not look like something that is totally beyond a crowdfunding budget | 18:13 |
| ssvb | mafm: https://www.youtube.com/watch?v=mD-njD2QKN0 (around 45:00) | 18:14 |
| ssvb | mafm: also https://www.parallella.org and various bitcoin miner startup companies managed to arrange manufacturing of their own ASIC chips, so this seems to work in practice | 18:16 |
| ssvb | Finde: 6x6mm seems like a relatively big chip | 18:18 |
| mafm | ssvb: so according to what you and Finde say, the openpiton needs to go through the testing batches first? | 18:20 |
| ssvb | mafm: don't pay much attention to what I say, I don't have first hand information and just found it on the Internets :-) | 18:22 |
| mafm | ssvb: olofk also said that openrisc would not be ready for such cpu-cards because it needs to be made ready for ASIC, tested and so on, so I suppose that all of these have their problems | 18:24 |
| mafm | before being "mass"-produced | 18:24 |
| mafm | since opensparc was a commercial effort before, and tape-out is mentioned in openpitor, I was wondering if they were a bit further ahead :) | 18:25 |
| ssvb | mafm: the RISC-V people seem to claim that their designs are already ASIC proven, and I'm looking forward to what http://www.lowrisc.org/ is eventually going to offer (they need a whole SoC, not just a CPU alone) | 18:30 |
| mafm | ssvb: yeah, I'm also looking forward to that, but let's see :) | 18:40 |
| kc5tja | What's funny re: OpenSPARC is that SPARC is essentially RISC-I. :) (I believe it's based on the RISC-I architecture.) | 18:49 |
| kc5tja | RISC-V is definitely ASIC proven; however, the ASICs were student projects, and not released to the public. SiFive is probably the closest at this point to getting workable, commercially available silicon out the door. | 18:50 |
| kc5tja | But even then, they're catering towards custom silicon. | 18:50 |
| mafm | yeah, agree with kc5tja | 19:02 |
| kc5tja | Sometimes, I question whether or not I should have gone with RISC-V for Kestrel-3. A MISC architecture CPU (for example, a CPU optimized to run Forth) would have been substantially simpler to design and go with in retrospect. | 19:04 |
| kc5tja | I should have stuck to my guns. | 19:05 |
| kc5tja | The opportunities RISC-V offered (and still offers) is very appealing, though. | 19:06 |
| mafm | kc5tja: yeah, but things are coming sooooooo much slower than I expected... and I think that I'm not the only one.... | 19:07 |
| mafm | well, time to go to bed for me, night! | 19:20 |
| kc5tja | Night | 19:20 |
| * ZipCPU|Laptop just looked chat commands | 21:44 | |
