Re: APU FPU in Virtex ppc405

I have been checking and it seems that the APU FPU patches will give 
some headaches now, so I will probably wait until they merge them with 
the official GCC release. In any case, it seems that the FPU restricts 
the PowerPC and bus frequencies to a max of 200/100.

Anyway, thanks for the info. I will try to keep track of this in case of 
an update.

Hi,

 I have just heard that Xilinx has freed the FPU module for the PPC
architecture in EDK9.2i. WIll I be able to make it work with my
Secretlab Linux 2.6.24rc3? Will the eldk toolchain for PPC_4xxfp work?
Will it be just a matter of integrating it with the XPS BSP?I make an
extensive use of floating point in my applications and this will be
really useful.
    

It's been 2 years since I last played with the FPU core.  At the time
it wasn't a complete FPU so the eldk 4xxfp toolchain would not work.
I had to build my own.  I don't know if the new core is a complete
implementation.

Cheers,
