for ppl like me who don't know shit about risc, cisc, arm and all the goods:
let's look it up on the internet shall we

Having read this I'm with Guyver here, I quess. (but then again, I'm a lousy reader and should have considered reading it again, and reading some more on the R800 stuff... oh well)

you might even wanna google with these parameters, interesting!

define:CISC

and

define:RISC

Quote: ARM has LDIR... I'm curious - which ARM version is this and which command are you referring to? LDM/STM on an ARM is hardly the same as LDIR on Z80. As far as I know ARM does not have memory->memory copy/move commands at all.

You are right, it's not the same as on Z80. In fact, it's a lot more complex!
And ARM's SWP is a read-modify-write instruction, another CISC-like feature.

My point is: Just because a processor has a few CISC-like features, does not mean its architecture (and I don't mean Instruction Set) is CISC!

ARM has a lot of CISC features, but it's still a RISC CPU. The same counts for R800.

Quote:

Funny how you say you are willing to discuss this, but can't come up with any arguments.

I haven't heard even one single argument from you either. I mean, "R800 is RISC, it's the design, the name and the fact that it was always presented as a RISC CPU." Uhm, oh.
design: only the implementation is somewhat 'risc-like'.
name: non-argument. that's just marketing.
presented as risc: non-argument. just marketing.

In short: risc is about the architecture, what the cpu looks like from the programmers' perspective. In my humble opinion of course.

Quote:

Well, the accumulator one... but that's it... and it's not even a good one, because it's implied by the instruction set. It has no bearing on the actual design of the CPU.

That's the point. The architecture is RISC or not, the implementation is not that important. (Since every modern CPU implementation uses the same design principles anyway). Btw: design is both architecture and implementation of course.

Quote:

Everything about it [6502] shouts CISC!

Yes, but more risc than Z80... The use of RAM instead of registers is just an implementation issue

Quote:

You really should do more research, otherwise even more people will start thinking you're seriously lacking in the intelligence department...

If they will do some research they will notice I am right. If they don't and think I am "seriously lacking in the intelligence department," there isn't much I can do about it, can I? Maybe they can convince me why R800 is RISC...
If "you're stupid if you think R800 is not RISC" is an argument why R800 is RISC, then something went wrong here...

I think architecture is important (instruction set, register set and such), GuyveR800 thinks the implementation matters more to determine a CPU is RISC or not. Nice.

Ro: I could point you to a lot of Internet sites that support 'my' view. It wouldn't mean much of course, because for every view and opinion there's a hundred websites.

Ah.. so you've reached the point where you have to start twisting my words and ignoring most of what is said.

This discussion is over...

As for websites supporting your view... There are also websites claiming no holocaust took place in WW2.

'nuff said.

Well, for me being a total dipshit about R/C-ISC stuff (I only know the RISC game kicks ass, but that's some other story I suppose) I just had to do some quick research on the net (thaz what it's for, not?)

In my opinion; both are you are dead wrong and totally right on this issue. I don't know, neither do I care that much. It's interesting to see this *hot* discussion getting slightly out of hand again. It's funny seeing 2 ppl fight about what a procesor should be labeled at. Maybe some other clever mind can shed some light on this sub?

(oh, and don't even start flaming me guys, I take no site nor do I point any finger, start calling any of you a total no-no-whimp or what ever. I'm just as curious as the next idiot )

cheers dudes!

No. ahh, well,... You're not even trying to see it from my point of view, are you?

Quote:

I already said: "It wouldn't mean much of course, because for every view and opinion there's a hundred websites."
Comparing "r800 is cisc" with "there was no holocaust" is pretty pathetic. It would be nice if you wouldn't do that. What are you trying to say here? Since R800==CISC...

Quote:

'nuff said.

No, too much. There was no need for personal attacks.

Quote:

Every clever mind can see... never mind
It would be useful (and impossible, I guess) to come up with some definition of what RISC is.

Quote:

I will flame you. You just wait.

sjoerd, don't tempt me; I'll have Wolf bite your leg off !

yeah, and I send my opa to give you 5 across the eyes...

*hgggggggaaaaaaaaaaappp!*

*munch-munch-munch*

More on topic: does anyone know where to find information about the R800, like the complete instruction set. Googling for R800 doesn't bring up much useful...

See, you don't even know what you are talking about!!

I knew you would say something like that... No, I didn't see that. Very helpful, thanks.

Whatever

Anyone else willing to share some info?

And you continue to twist my words, being hugely offensive at that... Exactly how pathetic are you? How low can you go?!

The last few posts you made about 'needing a definition of what RISC is' and needing 'information about R800' clearly show that you have been discussing this whole topic (and the previous one a few months ago) with almost no relevant knowledge!

It seems I was right, you really are nothing but a TROLL...

Euh, guyver... u know I'm gonna say something, right?! keep it cool man.

Why not point sjoerd out to an instruction set. I know you got one, not?
