ARM11 / VFP development


ARM11 / VFP development

Postby hm » Jul 16, 2007 @ 6:11am

I am working on porting some of my applications to an ARM11-based system with the vector floating point unit (WinCE 5.0). Looking through the documentation, it seems that the current VS.NET toolchain still does not support the floating point hardware. What are the best alternatives? Is there any 3rd-party compiler that would work? Or are there assembly language math libraries?

Thanks,
HM

Do a lot of PDAs have ARM11 CPUs?

Isn't getting ARM11 fully up to speed kind of a waste of time because intels mobile x86 CPU is just around the corner, which will probably have automatic floating point, and possibly run native windows apps 8O How awesome would that be.

Hi Hans-Martin,

did you have any success using VFP on the ARM11?
We got a Moto Q9, but as soon as I activate the -QRfpe- compiler switch in VS2008 the application crashes with an illegal instruction error.

Looking into the dissambly I find that the following instruction is causing the problem:

flds s0, [r3]

Any ideas?

Daniel
