Okay I think I can clarify this: Electrons trapped in the gate (when storing a 0) come from the substrate. The substrate is connected to ground, and the “lost” electrons are replenished. So yes, net chip weight grows when 0s are written. Ho

So glad someone else also knew about this connection :) Details about Denver are pretty minimal, but this talk at Stanford is one of the most detailed I’ve been able to find for those interested. It’s fascinating stuff with lots of similari

This is a pretty disappointing article with some very questionable examples. The Imagination Technology example in particular is poor since they were a supplier of intellectual property, not physical goods. So Apple’s usage of them as a sup

I'll give you an alternate take: the compute power available to EDA software has been roughly scaling at the same rate as transistors on a die. So the complexity of the problem relative to compute power available has remained somewhat

Not to mention that in-house silicon is all about economies of scale, this is even more of a puzzling move

Performance is agnostic of ISA. Apple's custom designed cores do indeed have a massive performance/Watt advantage over x86 based designs and happen to be using ARM. However, it's not impossible for an x86 CPU to be designed

That's because you're locked into the x86 paradigm. Look at the leaps and bounds Apple is making with performance/Watt by moving away from x86. This is the cost of legacy.

While I agree the issue is most certainly real, I feel that Apple Silicon is the scapegoat. Computing platforms need to evolve in order to progress, and sometimes the burden lies on developers to keep up. I think this is more of a story abo

And I bet you physicists argue that transistors are just abstractions of semiconductors

I don't think anyone suggests using C as an alternative for microarchitecture classes. C still remains one of the best ways to access hardware relative to other software languages. No language is "how computers work" unless

Radix-4 modified Booth encoding to reduce the number of partial products and then a sort of modified Wallace tree using 4:2 compressors (or some sort of 3:2 & 4:2 compressor combination based on technology node). There is another type o
