Need millions of transistors, not dozens. :) To me the biggest barrier is in tools. I'm still looking for the caltech tool and language which really helped in thinking in this way, and I did find it on github once, and it still seemed developed.... And the field is not entirely dead, after all. I keep meaning to pick up one of the new risc-v boards. Here's a async design of the risc-v... in GO of all things. (I also really hate the universal adoption of java amongst the circuit design folk... and I really loved the prospects of chisel, except for the jvm dependency): https://www.inf.pucrs.br/~calazans/publications/2017_MarcosSartori_EoTW.pdf in the risc-v world, well, it's still trundling forward. https://www.lowrisc.org/about/ This is pretty neat - standby is 2uA: https://greenwaves-technologies.com/en/gap8-product/ And pulp is pretty neat. https://pulp-platform.org// Still, I liked xmos's stuff... rexcomputing hasn't surfaced in a while In the last weird hardware embedded news of the day, you can get a old intel compute stick for 34 dollars on ebay. https://www.ebay.com/p/Intel-Compute-Stick-STCK1A8LFC-Intel-Atom-Z3735F-1-33GHz-8GB-PC-Stick-BOXSTCK1A8LFC/11020833331?iid=153273128090&chn=ps they were painfully slow but fit on your keychain. The most modern version of this design is https://www.amazon.com/Intel-Compute-Computer-processor-BOXSTK2m3W64CC/dp/B01AZC4IKK/ref=sr_1_4?s=electronics&ie=UTF8&qid=1543389564&sr=1-4&keywords=intel+compute+stick 2 cores, 4MB of cache, 64GB of flash... on your keychain. I rather miss vga in that it would be better to be able to screw these in... _______________________________________________ Bloat mailing list [email protected] https://lists.bufferbloat.net/listinfo/bloat
