I'm looking forward to
A new generation of micro boards. Perhaps a Raspberry Crumb.
Europe is trying to plant a flag in future chip development, slinging money towards low-power server silicon. Through its Horizon 2020 research collaboration, the European Commission pus published a solicitation for the project. There's nearly €375m on offer for the project, which looks to push more digitisation “outside the …
263 ARM based?
Actually the SPARC architecture has been licensed in Europe for rad hard and space apps.
In truth the smart thing to do is go clockless but that means you can't sell premium high clock speed chips.
Tough elements will be identify power hungry instructions (in existing ISA) and a low power interconnect for them at both board and rack level. What makes some instructions power hungry, and then either make the less power hungry or scrap them.
It's ironic that GNU and Linux, developed essentially in an instruction set monoculture, allow nearly any possible instruction set to leverage a large development environment, once you've hacked a code generator.
IIRC DARPA was doing something like this. Something about 1 PetaFLOPS for 5Kw?
