On reading this I thought "oh someone's doing the Green Arrays thing" but this looks like it pre-dates those CPUs by some time.

But as nobody has mentioned it yet surprisingly: https://www.greenarraychips.com/ albeit perhaps not weird; just different



The Green arrays chips are quite interesting in their own right. The ability to have a grid of CPUs each working at part of a problem could be used in parallelizing a lot of things, including the execution of LLMs.

There are secondary consequences of breaking computation down to a directed acyclic graph of binary logic operations. You can guarantee runtime, as you know a-priori how long each step will take. Splitting up computation to avoid the complications of Amdahl's law should be fairly easy.

I hope to eventually build a small array of Raspberry Pi Pico modules that can emulate a larger array than any one module can handle. Linear scaling is a given.


Nag nag...(meant inspirational in case you're unaware of it)...

Regarding Amdahl's law and avoiding its complications this fits:

(Not limited to SPARC, conceptually it's applicable almost anywhere else)

From the software-/programming-/compiler-side this fits right on top it:

(Also conceptually, doesn't have to be Scheme, but why not? It's nice.)


Agreed, they belong on this list. 18-bit Forth computers, available today and intended for real-world use in low-power contexts.
