Well, you can ask my friends: on the first link (Fightin' Spirit) you've all the names and you can try contact some of them.

Anyway, it's still irrelevant. You've written and continue to write a pile of logical fallacies which is absurd, considered that you're supposed to have a good amount of logic on your mind.

Again?!? PARROT!

I don't know if you're just trolling or it's because of some mental retardation which don't let you understand the following couple simple things:

1) I'm NOT an hardware engineer. My domain was and is about ARCHITECTURES (I'm highlighting you for the benefit of your limited mind. IF it works, but I have no hope anymore) and that's whay I did.

2) "the memory bus and the hardware implementation was driven by the owner of the company

They were his hardware engineers that reported that what you described was possible.

So, you continue to MYSTIFY writing piles of LIES about me! WITHOUT proving anything, of course.

In fact, I've replied to ALL that you've written 'til now but you, instead, have continuously cut A LOT of stuff WITHOUT giving ANY answers to the bullsh*t that YOU actually have written and neither replying to Matt's questions.

You only have time to repeat like a PARROT exactly the same things: a pile of logic fallacies which should prove something (but only your limited mind) AND the same set of LIES about my alleged responsibilities on the TiNA project.

But, again, just WORDS. EMPTY WORDS specifically.

Don't you see how ridiculous you're?

But if you want to continue I've absolutely no problem: who am I to stop you showing how a dumbass you are? Go ahead!

Bobcat used a better production process and it still sucked at lot at performances, compared to the Atom.

Reminder, 45 nm Atom is an in-order X86 CPU while 40 nm Bobcat is an out-of-order X86 CPU.

AMD's Bobcat-based E-350 (40 nm) beats Intel Pineview Atom D510 (45 nm).

Both Bobcat and Pineview used similar process tech in the 40 to 45 nm range.


AMD's performance target for Bobcat was 90% of the performance of K8 at the same clock speed and our Photoshop CS4 benchmark shows that AMD can definitely say that it has met that goal. At 1.6GHz the E-350 manages to outperform a pair of K8s running at 1.5GHz in the Athlon X2 3250e
- Anandtech

For X264 benchmarks, Bobcat-based E-350 beats Intel Pineview Atom D510.

For 3dsmax 9, Bobcat-based E-350 beats Intel Pineview Atom D510.

For Single Threaded Cinebench R10, Bobcat-based E-350 beats Intel Pineview Atom D510.



Intel's Pineview Atom D510 sucked harder.

Your narrative is FALSE.

So and in short: those experienced engineers completely failed...

Both of you don't know the context of the AGA development timeline.

READ https://www.landley.net/history/mirror/commodore/haynie.html

From Dave Haynie.

When he (Ali) got to Engineering, he hired a human bus error called Bill Sydnes to take over. Sydnes, a PC guy, didn't have the chops to run a computer, much less a computer design department. He was also an ex-IBMer, and spent much time trying to turn C= (a fairly slick, west-coast-style design operation), into the clunky mess that characterized the Dilbert Zones in most major east-coast-style companies.

He and Ali also decided that AA wasn't going to work, so they cancelled both AA projects (Amiga 3000+ and Amiga 1000+, either one better for the market than the A4000 was), and put it all on the backburner, intentionally blowing the schedule by six+ months.

They cancelled the A500, which was the only actively selling product ever cancelled in C= history, to my knowledge, and replaced it with the A600.

The A600 was originally the A300, George Robbins' idea of a cheaper-than-A500 Amiga; a new line, not a replacement. Sydnes added so much bloat, the A600 was $50 more than the A500, $100 over the goal price.

--------------------------------

With a fast enough CPU with 32-bit fast memory, the AGA dumb frame buffer role is sufficient for Doom.

Without a suitable compute power, AAA chipset wouldn't solve the Doom problem.

Commodore UK MD's David Pleasance advocated for accelerated CPU/Fast RAM equipped A1200 bundles, it was rejected by Commodore International's management.

Dear Cesare Di Mauro,

you call yourself "Amiga and CPU expert".
I think the question what you have as self proclaimed expert done in the last 5 years, or in last 10 years is justified.

Who has seen you develop anything for Amiga in the last 5 years?
Which Amiga demo party did you participate?
Which new game did you develop?
Which Amiga tool did you develop?

All I see from you are 2700 posts here.
And in these posts you claim to be an expert.

No, a game in 90th of some of your friends, where might maybe have participated or not - where no one can say today how much you really participated, sorry this does not convince us that you are an "Amiga and CPU expert".

Since the 90th is very long time now.
A real Amiga programmer would have had enough time to write hundreds and dozens of games by now. Where are yours?



You said yourself that you would have developed the world best CPU architecture, better than anything from INTEL, AMD, MOTOROLA or IBM.
These are very strong claims from you but again there is no proof of anything.





What we all know about you are your false claims about the TINA Amiga project.

Dear Cesare Di Mauro,

you not only participated in the TINA website.
You were named on the TINE website as the lead developer with the well sounding title "Amiga and CPU expert"

But did you only advertised this fake project on the TINA forum? No.
You advertised it there, explaining people how great it is.
But you also advertised it here in Amigaworld.net with many posts,
and you posted on very many Amiga forums worldwide about,
and you did several interviews about this project too.

In all these interviews you posted false information advertising a fake project.
In all these interviews you lied to the Amiga world.

But you claim you did not know that all this was fake?
While you posted for weeks and month on forums in the whole about it,
you could not know that nothing was right and all was wrong in your posts
as you had not invested even some minute to read the Spec of the FPGA you used?

Should we believe you that a real CPU expert would give dozens of interviews
knowing that he has no clue about what anything he claims in these interviews
but he does not even care to read at least a little bit of documentation before the interview?


Dear Cesare Di Mauro,

we can all see that you either purposely lied again and again to the whole Amiga community,
or you did spend month posting totally false wrong idiotic nonsense - because you not cared to inform yourself.

If we look at your 2700 posts here we can see the same again and again.
You posts false claims, either because you did not inform yourself or you did this on purpose, only you know the reason.

But no ternary instructions? Like fadd.s f0,f1,f2. Looking at your Mandelbrot example it should gain a lot in terms of code density (those ternary instructions should use a 3 bytes encoding) and, especially, performance.

Just to be clear, the Mandelbrot code is not intended to be particularly performant, rather it's there as a test bed. There are versions which expressly use non-register addressing modes (e.g. stack, static etc) so that the relative difference between these can be assessed.

Ternary operations drift further from the 68K familiarity zone. I'm not fundamentally opposed to this, but in this example, ternary only makes sense as a register only variant. Having to evaluate three full effective address cases is a lot slower. One example I'm considering, however, is a multiply-accumulate operation, e.g. fmac.d fp1, fp2, fp0 --> fp0 += fp1*fp2

@Karlos

Also for 3 byte register to register encodings, you can easily define quaternary operations since the opcode needs only 1 byte. Those may be harder to find, but a general purpose multiply-add (as distinct from multiply accumulate) may serve as an example.

Dear Cesare Di Mauro,

you want to call yourself "Amiga and CPU expert".
And you try to make us believe you with a game from the 90th where you claim to have participated?

The make a game you need experience and an experience developer does not just fall from the sky.

Let us look how a typical Amiga programmer career used to start in 80th and 90th.

A school kids got his Amiga and tried to learn coding.

The kid might code some small effect.
Maybe the kid will code a scroller?
After this maybe some Copper bars?
Then maybe a check pattern effect?
Then maybe a star field?
Then maybe a Sinus scroller?
Some Vector Balls?

and so on ..
The kids will get more experienced with every little demo or intro or effect it will code.

In the 80th and 90th the were so many Amiga demo groups.
As the kid shows that it can code, the groups will offer to join them.
The kid will tons of cracktros and get more experienced.

Maybe the kid will learn how game are done by cracking some.
Maybe the kid will write a few trainers for some games.
Maybe the kid will write a few helpers tools like disassembler or freeze tools, or packers..

The kid will go to many demo parties and participate.

In any way the kid will most likely create a long trail of dozens of demos he wrote, dozens of games he trained... before the kid got the experience and skill to even code a game.


And after doing one game, more games will come.
Companies will come to you and ask you todo stuff.
After the Amiga scene you might get offer to develop software for big businesses or SONY or PC game companies will contact you and offer you a job.

And when Kid got so much coding skill - why should it stop coding?




Dear Cesare Di Mauro,

your story that you wrote a complete game without any learning history of doing hundreds of demos and cracktros before and without using your Amiga coding skills afterwards does not sound realistic to me.

It looks to me like your Amiga background is all fake - the same way as your TINA project was all fake.

@kolla

Burns unit!

This Gunnar is a troll. He doesn't answer technical questions and the only technical statements could be easily copied from the Apollo core forum. He makes too many number and language mistakes. He isn't clever enough with his attacks and he is too persistent with them. He repeats himself too often. The repetition, persistent attacks and writing style reminds me more of MEGA_RJ_MICAL.

@matthey

Dear Matthey,

We know that you are an expert in the trolling topic.
Are you not one of the most famous Amiga armchair CPU experts,
and very proficient in copying content the Internet to spin your stories around?


But is openly calling out a liars trolling?
Does the Amiga community really need self proclaimed Amiga and CPU experts?



Dear Cesare Di Mauro,

you are of course never responsible for anything.

When you post untruth about the Apollo CPU then you are never responsible,
but the Apollo-Team is responsible as their documentation was not clear.

When you post fake stories about TINA and say the untruth in many interviews to Amiga fans,
then this is not your fault, its the fault of your friends which not explained you the Altera documentation correctly.

When you stopped the TINA project, then this was not because the project was unreachable and all your promised goals were vapor, no of course not, responsible was your employeer who did not allow you to continue to work on TINA. Shame on him!

You posted this excuse even in this forum here:
https://amigaworld.net//modules/newbb/viewtopic.php?topic_id=38258&forum=25#720929

@Gunnar
In all the e-mails I have from Gunnar, his initial greeting was never "Dear". Your ruse was pretty good but the more you typed the more you gave it away. Your writing style resembles that of MEGA_RJ_MICAL more than Gunnar von Boehn no matter how much you copy and paste from him.

@matthey

Dear Matthew Hey,

Would you call yourself an CPU expert?
When I read your posts here, you get never tired to tell us your wisdom about CPUs and abouts ASICs and FPGAs. Reading this I really get the impression that you think to know a lot about these topics.

Can you tell us where you got your experience?

Did you work on some major CPU designs e.g. for some big companies like INTEL before?

Or are you more self educated, are you reading a lot on e.g. Wikipedia?

How practical is your knowledge about ASIC design?

How much more practical experience do you have in this regard than about flying the Space Shuttle, or about how to win the Super-Bowl?

@matthey

What if MEGA_RJ has been Gunnar all along?

@kolla

What is everyone here is Theirry talking to himself? :o

@Gunnar
Is Gunnar your new developer persona or are you going to return as MEGA_RJ_MICAL? Honesty, Gunnar is pretty boring as far as a twisted developer persona theme goes. You could do PURPLE_HAZY_DAVE, CARL_THE_REBOL_SASSENRATH or DALE_BAD_AMIGA_LUCK.

@matthey

Dear Matthew Hey,

this thread here was started with Cesare Di Mauro calling you:

Quote:

@matthey: I think that you're the most competent and active expert about this topic. Would you like to contribute?

We know that Cesare Di Mauro, likes to call himself "Amiga and CPU expert".
While no one has seen any proof of Cesare Di Mauro being an Amiga and CPU expert yet.
What we see is that Cesare Di Mauro likes to post thousands of posts, pretending that he would know something. What the Amiga community also has seen, is that Cesare Di Mauro was posting for month and year fake news about impossible vapor Amiga projects, and was lying to the Amiga community in many interviews.

Seeing Cesare Di Mauro, posting like this to your,
this gives us the impression of one conman is calling another conman.


Dear Matthew Hey,

You are a very active poster.
Very much like Cesare you like to pretend to be a CPU and ASIC expert here.
Looking in detail at your posts, its obvious that many of your posts are technically not correct.
Mistakes can happen, and if someone writes thousand of posts even an expert can be sometimes wrong.

Please help us understand if you are a real CPU expert, having some real experience in the areas that you talk about, or are you as some people say, only a monday quarterback - talking out of your ass all the time.

Please tell us more about your education?
What did you study, was it CPU design by chance?
Do you work for IBM or INTEL in ASIC design?
What job are you currently doing?

Dear Matthew Hey,

What is your work profession?



Dear Matthew Hey,

You make many claims and posts here in the forum.
I've the impression that many of yours posts are technically not correct at all.
I think you spin your own reality about personal grandeur and about a knowledge that you not have in reality, and that you in reality tell the people total nonsense.


The question is "Who are you?"

Are you an experienced CPU designed working at INTEL,
or are you farmer from Kansas, who in reality has zero practical experience and zero knowledge about CPU design at all?

Are you telling wisdom to the people here, or just nonsense?
