1  Hardware and U-Boot firmware / Hardware / Plug computer with FPU? on: September 28, 2010, 03:13:23 AM
Hi there,

I have a dream (no pun intended) to run SqueezeBoxServer and a parametric equalizer on a plugcomputer.
An easy way to implement this, would be to simply install the brutefir (and fftw) packages readily available for Linux.
Now, these packages require a CPU-architecture with a FPU to run acceptably efficient.

Is there such a thing as a plugcomputer with a FPU? Or are there plans for any? Where could I get it?
The only alternative I see, is to use a traditional server on a Desktop computer with all its downsides.

Best regards,
-thomas

Thanks. That is exactly what  I thought.
I got a reply from a vendor that both the fftw and brutefir are available for the pre-installed Ubuntu version 9.05. I guess they just checked if the packages were in the repository.

So my conclusion is that perhaps the packages will compile, but brutefir will run hopelessly slow because there is no FPU. Am I right?

PS: Running FPU operations on a CPU without the built-in instructions must be hopeless. Moreover, who wrote the libraries? That must have been a very odd job and of very little general use.

Hi there,

Is it possible to compile and run the brutefir  (www.ludd.luth.se/~torger/brutefir.html) for the SheevaPlug?
I guess the critical library is fftw (www.fftw.org)?

Brutefir is easy to install on a Desktop machine running Ubuntu (apt-get install brutefir), but I am not sure whether the ARM architecture is supported.

If it *is* possible I could use it for running a parametric equaliser for Squeezebox Server.

Cheers.
