You may get more out of the Patterson and Hennessy book first, thats how a university curriculum would normally work. https://www.amazon.com/Computer-Organization-Design-RISC-V-Architecture/dp/0128203315/

duck monster posted:Do Z80s still turn up in the wild anymore? Back in the late 90s/early 2000s I worked at a company where we where often reverse engineering a lot of embeded stuff to add our own control to it., and Z80s would turn up a lot. To the point I even wrote my own OS for them that was kinda forth based, but could do cross cpu process internonnect via a 2 wire (Actually now I think about it, 3 wires, in, out and latch) message passing system. It was kinda neat but never got anywhere. I loved those crusty old processors. Very easy to write assembler for. https://www.digikey.com/en/products/filter/embedded-microcontrollers/685?s=N4IgTCBcDaIFoEsA2B7A5iAugGhAVilAAcoBGXIkyPABgF86g They appear to be at the “well I guess if you want them we’ll keep a line open” level of pricing ie $5/1k up to… whatever this is https://www.mouser.com/ProductDetail/ZiLOG/Z8018220AEG?qs=ZJLcQYZ9%2F%252B57UM50szoAJA%3D%3D

The GMC Yukon and Polestar 2 both feature one of the slowest CPUs you can buy today in any form factor. hobbesmaster fucked around with this message at 23:29 on Jan 13, 2023 |

…those are actually quite powerful by embedded cpu standards.

To be clear I was speechless that someone reviewing an embedded product would be so unfamiliar with it. The CPU speed thing is comical for example.

It’s not a strawman, it’s an example of how a big push for a radical change from x86 was unlikely to gain market acceptance. Even with the example of arm, there’s a lot of armv8 processors running in the aarch32 execution state out there.

Subjunctive posted:Is that proposal likely to go anywhere? Seems like a pretty hard case for national security to trump the first amendment for someone writing down how to fold proteins or whatever as an ISA extension, but I guess it’s possible. What was the government’s reaction to the proposal? I’d assume it’d be like 40bit encryption which I’m sure is something you’d prefer to forget.

Subjunctive posted:Did I miss some major developments, or is the author of this architecture book perhaps unreasonably generous in his assessment of RISC-V’s market success? The security processor in google’s pixel probably means they can count all of those by vague technicality.
