Casanova Posted October 30, 2018 Share Posted October 30, 2018 Fellows, i'm doing some bech tests with this FPU/Math Coprocessor from IIT company. It's basically a cpu dedicated to process floating point unit operations. Since 486dx they were embedded in this cpus, but in 386 era they were provided separately by some companies, IIT is one of them. Any more information you guys need i'll be more than happy to provide @Strunkenbold Quote Link to comment Share on other sites More sharing options...

Crew Strunkenbold Posted November 19, 2018 Crew Share Posted November 19, 2018 Well that is something unique for sure. However if I understand correctly, those Co processors can just work with a main CPU. Is any program able to detect those combos? I mean, I dont know if it makes sense to add co processors at all to the db, probably need another opinion from Antinomy here. Quote Link to comment Share on other sites More sharing options...
Casanova Posted November 19, 2018 Author Share Posted November 19, 2018 (edited) @Strunkenbold Yes, they can be detected by software, but the information is restricted to "math coprocessor present/yes". In resume, they can't work separately from main cpu, but once installed it can give more than 32x faster process abitity to calculate decimal numbers. As a matter of fact, when you run superpi using a fpu processor it is this cpu himself that do all the calculation work, not the main cpu. It works at the same frequency that main cpu works, no matter if they are sharing the same crystal oscillator or using it's own crystal, it will only work at same main cpu speed.
