Sehr gut zur Nutzung diverser Tools von MiNT mit 030 Beschleunigern ohne FPU ...

Lukas Frank:
Neue Version wobei auch der MiNT Kernel die FPU erkennt.

Arthur:
Eine tolle Sache... wenn die Software unbedingt auf eine FPU besteht. Wie viel % erreicht die Emulation ungefähr?

--- Ende Zitat ---

Mich würde der Linpack-Score interessiere: https://github.com/czietz/linpack-atari/ (Natürlich unter Angabe, welche CPU bei welchem Takt zum Einsatz kam.)

Lukas Frank:
Linpack läuft jetzt auf einem MegaST4 mit 50Mhz 030 TF536 so knapp eine Stunde ohne Ergebnis bis dahin ...

Gembench zeigt so was um einen sehr niedrigen Prozent Bereich (1%-4%) an FPU Geschwindigkeit.
