Re: A New Golden Age for Computer Architecture
#2I'm trying to think of what are some neat computer architectures out there.
Chuck Moore's "Green Arrays" is kinda cool and so is the Parallela board.

#4Alot of what they suggest seem to be better solved in the domain of compilers and microcode translation on the fly.

#5I remember being excited about The Machine [1] from HP:
"The Machine will be a complete replacement for current computer system architectures. There will be a new operating system, a new type of memory (memristors), and super-fast buses/peripheral interconnects (photonics)."
"HP says it will commercialize The Machine within a few years, “or fall on its face trying.”"
It seems later happened...

Re: A New Golden Age for Computer Architecture
#6Interesting article with a lot of great historical context. I think a significant part of the tl;dr is that the end of Dennard Scaling and trouble with Moore's law may mean that the best architecture will finally win out, rather than just the one with the best semiconductor design team behind it.
I'm a bit skeptical of the promise of DSAs, though it does seem we're already going that way. Curious what others think on that point.

– As announced by Intel on the launch of the new Itanium architecture.

#8> Today, 99% of 32-bit and 64-bit processors are RISC
> Concluding this historical review, we can say the marketplace settled the RISC-CISC debate; CISC won the later stages of the PC era, but RISC is winning the post-PC era
It is clear that his assessment is right, but isn't the 99% number too high ? Servers, laptops and desktops still run x86 and they are CISC ( unless you are counting x86 as RISC based on microcode )
> Many researchers assume they must stop short because fabricating chips is unaffordable. When designs are small, they are surprisingly inexpensive.
> High-level, domain-specific languages and architectures, freeing architects from the chains of proprietary instruction sets, along with demand from the public for improved security, will usher in a new golden age for computer architects. Aided by open source ecosystems, agilely developed chips will convincingly demonstrate advances and thereby accelerate commercial adoption.
It will be interesting if manufacturing also gets open sourced. There already seems to be a project attempting this : http://libresilicon.com/

Transputer. Hardware multitasking and link-communication and a very compact instruction set.

SOAR (Smalltalk On A RISC), though the conclusion there was mostly that a plain old RISC will do. I wonder if that is still true today.
