- nickpsecurity 11y agoDid you mean the main University group (s) that defined and implemented the ISA? If so, I agree they've done well. I especially loved that they open-sourced a 1+GHz 48nm core. Awesome stuff. I posted a link to Schneiers Squid thread today on a bunch of asynchronous chip work. One was a 180nm FPGA w/ several times Xilinx's performance and one a 40nm microcontroller. I imagine a combination of RISC-V with that async flow would produce one drool-worthy processor in price, performance, and NRE cost.
- thesz 11y agoCan you point out where the links are?

- thesz 11y agoThank you very much!
- kjs3 11y agoYeah...that 1GHz core could be the game changer as far as Open Source hardware goes. Seems pretty much anyone with an above average undergrad digital design competency has cooked up a core/ISA that ranges from the few tens to a few hundred MHz, but a real 1GHz core on a real process potentially puts it in range of the ARM/MIPS crowd performance wise (that is, out of "isn't that a cute toy" territory). I confess to not being particularly conversant with async design (it became mainstream after my time), but I'll definitely check out your links and see what I can learn. Interesting times and all that.
- nickpsecurity 11y agoMore interesting than you think: we have an open-source FPGA architecture out there now and cheap[ish] processes to implement it. http://pastebin.com/bakX4RRZ http://pastebin.com/bakX4RRZ
- kjs3 11y agoI thank you, sir, for this months reading list.
- nickpsecurity 11y agoYou're welcome. I have over ten thousand in all and someone just asked me for dome on making C programs memory safe. So if you like that too check back on my profile's comments in a day or so.
- kjs3 11y agoThat was me asking about memory safety, actually. You ever get to Atlanta, GA, I owe you a dinner and a beer.
- nickpsecurity 11y agoOh must have lost track lol. Appreciate it and might take you up on it.
