Re: [microblaze-uclinux] ucLinux with Microblaze 4.0



Hi Kevin,
Thanks for the reply!
But a little addition - "we all will cheer uClinux on MicroBlaze is indeed a wonderful thing....", as I'd hazard a guess that most other embedded processors do not support FPU's!!

:)

Hello John,

microblaze. Does anyone know if uClinux will see any performance improvement with this - My hunch is that there is little requirement for an OS to use floating point - and most likely it's avoided at all costs

OS (uClinux or not) have very little use for floating point barring a few esoteric I/O drivers (if you consider that OS) and specialized HW extensions for graphics and such.  The need for FP is in the application domain. Corrolary to the OS having no real use for FP, users have no real use for OS without applications that do useful things.  An OS without applications is little more than a curious piece of art, like a painting.

The point is that with FP, more applications will become available as they are more easily realized (not having to fake FP with SW or fixed point math). With the new better applications, the systems will seem more powerful and we will all cheer "uClinux is indeed a wonderful thing.  What can it not do?"
