ADOOM on A600 running 22-35 FPS

[ChaosLord]

I would be very surprised if a compiler tries to take advantage of the extra vector/integer hybrid whatever registers

What is wrong with having vector registers added?

 and 68k assembler fans are likely to turn up their nose also, Gunnar's new ISA is like trying to force a square peg through a round hole but he has decided that the square peg is better and that he will have it at all costs.

I am trying to understand what is the problem with the new ISA.

Could you give me some example instructions that are critical and should be added, but Gunnar banned them?

Did he add some good new instructions but chose stupid encodings for them?

Or ?

Remember I have no idea what has been going on with this.  The last thing I remember, I was telling Majsta what a good job he was doing in trying to cook up an FPGA 680x0 CPU (It wasn't very fast, he had just started) and now all of a sudden it seems Gunnar has taken over and Doom is running at 22fps on A600.

Bounty to open source that.

Luckily a Black & Decker Power Drill + Crowbar are cheap. :lol:

Gunnar didn't ban anything. He used ColdFire encoding space to add more integer registers which he unilaterally decided was more important than anything else.

If he overwrote the ColdFire instructions with different instructions then he BANNED the ColdFire instructions from working.

If he had left the ColdFire instructions unimplemented then you or I or any random person could add those instructions in later.

But to enforce the BAN, he overwrote their bitpatterns with new incompatible instructions that serve a different purpose.  Thus preventing their ColdFire use forever and ever.

Is there something about those instructions that just totally sucks?

If I would have had those coldfire instructions available to me in the 1980s, 1990s and 2000s then I would have used them and had faster code.  But I have put no thought into them at all for around 10 years.

Does Gunnar have a logical reason to murder the coldfire instructions?  Like they were stupid instructions?  Or they were to slow?  Or they bog down his ALU?  Or they consume to many read/write ports?  Or ?

If you license the core to 3 different parties then this does not save you time this creates more work for you. You have to support them. Each partner might use a different FPGA, different memory. So you need to help them to interface and to test/fine tune the memory controller.
Even is you provide standard industry bus interfaces - as Apollo does.
They will have many questions which you need to answer.

I have no secretary which could answer all these customer questions.
Therefore to be honest - I do not think that this will save me time but cost me time.

gunnar von boehn promised NatAmi faster than powerpc.

I do not want NatAmi with 060.  

I want NatAmi faster than g4 with PS2 level graphics, for 100 euros only.  

gunnar promised that in autumn 2009, everyone will be able to buy it.  

Gunnar overpromised many things but I don't remember any "for 100 euros only" promise.  Maybe you are referring to "CPU only"?

And the deal with "faster than g4" was actually "Mhz for Mhz faster than G4".

That means a 100 Mhz Natami/Apollo would be faster than a 100Mhz G4.  A 300Mhz Natami/Apollo would be faster than a 300Mhz G4.  And a 400Mhz Apollo/Natami would be faster at copying memory from Point A to Point B than a 2200Mhz G4 due to the spectacularly bad memory interface endemic to all publicly available PPC processors.

If you are going to criticize someone, fine, but be truthful about it.

What is the predicted price for the Vampire?


I have decided that the biggest technical problem for the Vampire is...





I don't own an A600 and never have.

In fact I have been trying to think up an excuse to buy an accellerator for An A500 or A2000 but I have no desire to accelerate those machines.  I only use old OCS/ECS machines to be 100000000% compatible with old games.

Seriously if I was going to buy an accellerator for an old ECS/OCS Amiga it would be for one of my A3000s.  My A3000 has an absolutely wonderful SCSI hard drive controller that magically loads data from Hard drive with around 0% CPU power.

My A3000 has 16MB of RAM which is a halfway barely usable amount.  It really needs more RAM.

My A3000 can "easily" be upgraded to have PCI slots with a Mediator.

My A3000 can then be easily upgraded to a 32-bit GFX card with 256MB of RAM which would be a barely usable amount if someone would fix the flaw in P96 that prevents the usage of half of that RAM.

An A3000 with PCI slots and a 256MB gfx card + an Apollo Accellerator would make a very nice gfx card machine.

Are there any plans to make an A3000 Apollo?


I could simply put my A3000s in the closet and get an Apollo for my A1200!  My A1200 already has the PCI slots!  My A1200 has a completely trashed out garbage HD interface called IDE.

What is the projected price range of the A1200 Apollo?

The Vampire 600 is available for 90 %&$#?@!%&$#?@!%&$#?@!8364;

Only 90%&$#?@!%&$#?@!%&$#?@!8364; !!!!!

I see now that this is all just your evil plot to punish me for not buying an A600 when I had the chance.
