Hi all, Here is my most recent 16 instruction set for concatenative hardware. Any comments would be greatly appreciated. /* * Released into the public domain...
Don't you think basic arithmetical operators would be useful, if this might eventually be actual and not theoretical hardware? If you only have and, shift and...
You missed the ADD instruction. Seriously, though, I do suspect that Chuck Moore has it right on this one... Use instruction slots in a larger word size, and...
... Why? ... Sure but that is just one instruction. Overall, having 16 instructions, means a much smaller chip with very very small power overhead. I'm not an...
... You overlooked add. With that we can perform all arithmetical operations without too much problems. Of course, this is not appropriate for a PC CPU, but...
... This is what Chuck does. The reason I think he's got it right is that 16 instructions just isn't enough for a reasonable programming platform, especially...
... A fascinating goal, and one which to my knowledge has not been attempted together with a high-level instruction set. ... Completely incompatible with the...
... I think the distinction between "high-level" and "low-level" is artificial, and rooted to firmly on the naivete of our predecessors. If we ignore it, we...
... I'm not really designing the thing to be implemented by hand, I would expect the programmer to use a compiler. ... That line of reasoning isn't accurate....
... Well then, "special purpose" versus "general purpose". Either way, IMO interesting. ... Ah, this is how I handled the 8-bit instructions I was required to...

First let me say, I really *really* appreciate all the feedback I have had on my past articles on Cat. So far all my article submissions have been rejected....

Hi William, Thanks. I've responded to your comments below and already started tweaking the article as per your suggestions. ... Thanks. ... I can't say yet,...

I'll be quick here, as I haven't the time I wish I had. The introduction seems weak. Simplicity doesn't come from a low number of concepts. If it did, the...

Hi John, Thanks a lot for the comments. ... Sorry about that. ... I'm a little confused: a low number of concepts seems to be the very definition of...
