Hardware, Embedded Systems "In this article, I show at the transistor and silicon level. I've discussed the mathematics of the 6502 overflow flag earlier and thought it would be interesting to look at the actual chip-level implementation. Even though the overflow flag is a slightly obscure feature, its circuit is simple enough that it can be explained at the silicon level."

It's easy to forget with all these high level programming languages and modern operating systems used to launch the latest 3D games with the best A.I. bad guys that it's really ones and zeroes.

Maybe for end users, but I'd have hoped that most OSNews readers found that fact hard to forget.

I hope so, but during my life I have encountered a number of IT people that were seriously lacking any knowledge beyond their own speciality.

Most don't even know what a nibble is!

It's a sign of the times I guess. Many financial experts use cheap calculators and have no clue how my HP-12C works, nor had they ever heard of it. I have the HP-16C too, to get back to binairy.

Aren't they the snakes that used to inhabit that QBasic game which shipped with DOS once upon a time? :p


...In all seriousness, I can forgive people for not knowing what a nibble is; there isn't much need to deal with half-octets in most cases. But understanding that computers process in binary is pretty much covered in the 1st chapter of "The Idiots Guide To Those Magic Computing-Boxes".
