As Ivan just pointed out to me privately, I meant "is the stack machine model revisited", not "queue". Queue and stack machines are quite different things. But the rest of the argument holds.

I like this guy and his presentation style, it is good to see someone delivering seriously on an old idea: queue machines. (The "Belt" is the queue machine model revisited. I can't see a theoretical breakthrough here). But th

C does not expect addressable registers. This architecture seems quite appropriate for C!

Virtual memory can be used as "poor man's GC" only with languages with a variable number of bits in pointers (references). If you have a fixed number of bits in your pointers, like in C & C++, then you will run out of ad

".exe" and ".com" files are basically two different file formats for executable code. Note that DOS selects the file format not based on file name extension but rather by looking at the first 2 bytes in the file. If th

Yes you are right, if that was marketed like the introduction of x64 it may work. However there is a big difference: the move to 64-bit words was something that was in demand when it was introduced. There was a market for it, with a very cl

We use just C extensions for now, very close to what Cilk does. 1) What is really important is to realize that dataflow variables (I-structures) are not in memory. So any language/library that gives dataflow semantics to programmers should

Except that would not show lower energy usage. To preserve backward compatibility, the cores would need to keep the logic that analyses data dependencies to continue delivering good performance to legacy code. To make any difference they wo

Minimum energy usage is very dependent on not activating more circuits than strictly required for a given computation. However a conventional processor pipeline will usually fetch instructions and begin processing them, only to realize late

The word "moonshot" is close to the truth, yet there are strategies to overcome the adoption threshold. That was precisely the topic of my PhD dissertation, and I concur that the Adapteva guys have chosen a sound approach. But Epiphany is n

On Android if you enable the numeric keypad as input method (instead of the standard keyboard), it will behave like you describe -- a variant of T9.

In France you can ask the store to erase the default OS install and be refunded of the price of a standalone OS X. So there you have it.

" it's valid for C code to define the main() function as something other than int." It's a bit more complicated than that. True, C defines two environments called "freestanding" (without OS) and "hosted" (with OS). As per the ISO specificat
