Is PowerVR chip (used in Dreamcast) a good one?

[lempkee]

whats the best design for usb keyboard/mice really? , anyone know? ..

as we all know how amiga and mac and pc acts under optical usb mouse etc, even on a 3ghz x86 , its slowing everything down!..

any thought? ,
and btw amidelf why is USB keyboard and mice a must? ..

eh? What?

USB is the next best thing to originally Amiga mouse and Joystick ports.

Forget PS/2 keyboards or mouse if you want to be a good drawer. I dont expect annyone going for the Amiga, Atari, Sega Megadrive, C64++ standards again. So USB is the next best thing to it all.

Knows anybody actually if there might be a new gfx chipset being developed from the makers of the PowerVR? Would be an interesting one for the A1.
I still think Amiga should develop a nice gameconsole aside the A1. They got the name for it and if it gets a bit publicity, it could sell very well.

I actually agree with you there. Could be a great and new marked, for those wich wants to buy a great computer from the start.

Lets say that:
Amiga 6000 became the next-generation Amiga
AmiCast or something for a next-gen game console

That would be nice! I am sure of it!

But why did you choose the PPC? I don't understand how it fits your needs!!

Check out their website, there are newer cores from them, such as the MBX.

USB == great way to turn that 3Ghz computer into a 200Mhz computer.

PS/2 ports are dedicated interfaces, and can be given Amiga-like control capabilities.  To do the same with USB takes a *lot* of glue logic, upping the price.

I hope you can back that claim up! My 3Ghz machine is not affected by the chain of USB devices and Hubs pluged into it!!

but every computer has to have at least USB 1.1 now, since 99% of all equipment uses it, and with good reason.

I notice fully well how much my 1.5Ghz Athlon does when using USB peripherals. Under heavy USB 2.0 loads, the Athlon is noticably slower than otherwise.  Of course, include an I/O processor and USB's shortcomings vanish.  (many motherboards nowadays do include one)

Noone is saying *not* to have USB.  I was presenting the arguement that USB is not necessarily the only way to do the situation.

And FireWire?

[downix]

Firewire works closer to how SCSI does, that is it has its own controller and doesn't need to continuously poll the CPU.

USB more like IDE without ATA, that is the more load on the system, the more work on the CPU.

That's why top-end Intel machines (and several machines from other vendors) have been including low-end IOP's to handle the load from things like USB.

[Speelgoedmannetje]

So I assume it's too expensive to use as a standard connector for everything outside the computer. (is it actually fast enough to use with a monitor or so?)

[AmiDelf]

USB isnt slowing things down at all. What are you all talking about? Ever used USB things on a Amiga? No problem at all!

Windows aint the best OS,.. so well. USB is fine and dosent harm your hardware if you unplug something when the system is on.

PowerVR chip in the DC was indeed powerful, and the Kyro/Kyro II for the PC are even more powerful. IN all honesty, I loved the Kyro II, tile based rendering is still a VERY good thing. As it only renders polygons which you see on the screen, instead of every polygon at one time.

Dreamcast games in it's later life were just as good as todays games on PS2 and Gamecube are.

Screen of Skies Of Arcardia for Dreamcast


Yes indeed. Dreamcast is powerfull thanks to its PowerVR chip. A Amiga with it, would blow lots of minds. With 512MB DDR RAM and 600MHz G3 PPC cpu and AmigaOS4. This Amiga 6000 could be "the" ultimate entertaining computer.

I will update everyone on how it all goes with this project.
