- matja 5y agoAnd not even a mention of AMULET (https://en.wikipedia.org/wiki/AMULET_microprocessor https://en.wikipedia.org/wiki/AMULET_microprocessor)
- nickdothutton 5y agoCame here to say this.
- Taniwha 5y agoNor this one: https://authors.library.caltech.edu/43698/1/25YearsAgo.pdf https://authors.library.caltech.edu/43698/1/25YearsAgo.pdf It was the original paper for this that got me interested in building silicon tools
- mahami 5y agoYes, but I thought that it could be interesting to look at research on the topic from 20 years ago to compare it with present progress.
- blagie 5y agoAsynchronous would work better, but we're unlikely to get there -- too big a change. It's like: * having ECC everywhere * having a single display standard (as opposed to HDMI/DisplayPort/USB-C/DVI/VGA/...) * some kind of architecture where a single bad expansion card (USB, PCIe, etc.) can't crash a whole computer ... and so on On one hand, no brainer. On the other hand, it hasn't happened. NVidia is breaking ground on the move to SIMD/MIMD-style architectures, as predicted at the same time, and only because it gives a 30x boost in performance. Async will probably net us a 50% performance boost or something.
- astrange 5y ago> * some kind of architecture where a single bad expansion card (USB, PCIe, etc.) can't crash a whole computer If you mean IOMMU, we do have that. It doesn't seem completely doable because someone could still plug an etherkiller into the card.
- blagie 5y agoI don't care much about hostile attacks. I just lost a few weeks until I debugged my computer was crashing due to a failing wifi card. I care about that sort of thing. That's totally fixable.
- astrange 5y agoEh, you probably already have the OS architecture for that. The vendor just isn't using it.
- dgellow 5y agoCould you add the publication year in the title of your submission?
- UncleOxidant 5y agoHas there been much progress? I remember hearing a lot about asynchronous logic circuits back in the 90s, but don't hear about much in the way of breakthroughs since then.
- mikeurbach 5y agoWe had the pleasure of hosting Dr. Manohar at a CIRCT weekly discussion session earlier this year. He presented much more recent work if anyone is interested. The talk and discussion was recorded here: https://sifive.zoom.us/rec/play/Bg99_niHh9OG_8uE_nhaz6otxvA02KEcvQkQWX18WK0DLgyt3jxBPOCC0T1j3CQyjxgDe5uHfE24FHV7.E4f1N6rb8E0_QPS9 https://sifive.zoom.us/rec/play/Bg99_niHh9OG_8uE_nhaz6otxvA0... EDIT: talk begins around 7 minutes.
