How does the PowerUP-accelerators actually work?

erm?=?

it works like this,  you do an ppc instruction (code) and the cpu works...wow..

there is 2 kernels for that , powerup (the first) and warpos (second and the best)

to them who ask such a question...hard to answer as its not a fantastic thing , besides you have alot of contextswitching between the 2 cpus and on a1200 u have contextswitching between the 3 cpus.

anyway to do ppc sw , then you need to do ppc calls, if thats what you wanted to know..

 the ppc wont do any work unless there is a tool or a game that takes advantage of it, ie just like an fpu, needs special commands to work.

also amigaos 3.x is 68k only , and the ppc wont be in use at all unless u install warpos or powerup and then later you need to install ppc datatypes and such...

and as ajk said...this is where os4 and morphos does a better job because its an ppc os.

i wont be suprised if there is a huge speed up when the os\s are finished.

downix:i agree with you on a few things , like mame ..but that is because of the coder, there is alot of sloppy work around and more will come now that we have faster hw plattforms.

but there is a few things, ever seen 3d render with pup? ...
ever seen new stuff by the same developers ?

the good ones left sadly, and atm there is mostly only bloatware to port...ie like later versions of mame (which is a big bloat atm ;().

anyway i totally agree with you on it beeing faster for a few things, but by far all.


patrik: i will answer you in the morning if no other has posted some answers.

cheers

patrik: i didnt make a kernel for it so basically your questions are way too deep for me.

bloodline: if you look whats been said then u would know what i was talking about , as in his question wasnt very "spot on".

context switching is the biggest issue on the classic powerup cards and will allways be as long as we are stuck with an 68k os , sure its gotten better as whas pointed out in earlier threads, but its still a major prob.

(68k cpu does still a major job even if its a ppc app (when running amigs os with wos/pup).
