Indeed the emulation vector access is protected, supervisor mode needed, on a vector that no amiga-land software knows about it. Hard to break. At least not less than an 040/060/HSMath library.
About precision, sure, it then is enough or NOT for a given end-user. Your choice and need, i have no problem with that. That said, even 32 bits of precision would be enough for real life usage / games and demos applications, such as in most of the consoles (PSX,...). For Quake or let's be mad Gran Turismo, 32 is enough, like any games on such machines. If the point was to use the vampire for scientific researches, then sorry about that, it is not intended to.
About emulation, that is for me infinite discussion where FPGA coding is NOT emulation! I wont argue not a single one more on this.
At end, i'm the one who had bring the more technical data here about this fpu topic, I could also bring more about for example the 100% pipelined feature. Hope it helps the people for who the vampire is targeted to. The team is not trying to convince everybody but to bring a fpu solution at best as it could be on a given board for his customers.
