The RTKLIB author T.Takasu and A.Yasuda have  ported RTKLIB to a BeagleBoard which has an ARM Cortex-A8- with 1 GHz and floating point, I do not know if double or single precision.

I plan to move in this direction also, may be using a hardware less powerful but cheaper.
Raspberry Pi
The SoC is a Broadcom BCM2835. 
This contains an ARM1176JZFS, with floating point, running at 700Mhz, and a Videocore 4 GPU.

I am waiting, anxiously,  the RTKLIB 2.4.2 version with RTCM-104 phase messages encoder to built a local base station as where I live there are no near NTRIP network ( less than 10km ).

good luck,
