Surprising POV test

[Guillaume Tello]

Hi,

I made the POV test on a CT60 that runs slower than on an Hades or Milan !!

They share the same processor (68060) but the CT60 is clocked at 95MHz,
much faster than the 60MHz Hades or 50MHz Milan.

What happens? Is there a library to load for faster FPU operations?

Here are the results of the POV test (in the middle of the page):

Can anyone help?

The Hades does load some FPU patch at bootup from the autofolder called
FPU__3.PRG and its from Medusa (Fredi). Not 100% sure what all it does, but
it seems to be required. You can probably find a copy of it at his website.

Jozsi sent me his results for a 80MHz CT60 and he gets 16 seconds for
his POV test with the Radeon etc..

How can my machine (95MHz) spend 86 seconds on the same problem?

That's a mystery for now...

I tried it: the patch loads correctly, but then, when I run POV3 I get
an error and the program stops.

The FPU-emulator is already installed by the CT60 firmware. Perhaps you
need to check your CT60-settings?

Something strange....

I renamed POV3.TTP to POV3.GTP and now it runs the test in 26 seconds
instead of 86....

Looks like the TTP managment takes some time..!!

Strange, so I tried the same trick, my time improved slightly. I sent you
new results.

I tried too, same time for me, 10 sec.

I update the page with your various results showing that POV is strange....

http://gtello.pagesperso-orange.fr/kronos_soft.htm

And more general results in the other Kronos pages with an Hades and my
CT60.

Hello everyone,

It is Christmas day and I just wanted to wish everyone here
a Merry Christmas and a Happy New Year. Hard to believe it is
30 years ago I became an Atarian and I have never regretted
it. Take care all.....

Bonnes fêtes!!!!!! Joyeux Noel!!
Best wishes from France to everyone.
I became an Atarian 24 years ago...
But I remember having played "Pong" in Spain in 75 ou 76. At this time
it surely was an Atari machine even if I can't remember (I was 10 years
old...).

Happy New Year to all Atarian.... May the new year bring plenty of
Atari hardware & software upgrades to you.

My dad told me that I spend over an hour at a shop selling Atari 8
bits.... when I was 10 years old.
But my very own Atari ST was 23 years ago, and it is still running
when I tried in back in Nov 2010 !!

Excepted for MagiC you not need program inside the AUTO folder for the
CT60. FPU 68881/2 emulation and unimplemented instuctions are added to
the TOS by the BOOT.

Inside the CT60CONF.CPX, boot / TOS, there are a popup with 4 choices of
setting for TOS Pexec and a cache 5 sec delais who disable caches when
the program start.
