[time-nuts] Raspberry Pi Competition...

[Bob Camp]

Hi

Freescale has had K60 modules out for several years now. No usb ethernet and they do have 1588 built in. Depending on just when and where you catch them they can be pretty pricy or about half that...

That is, not fully kosher floating point, but fast parallel processing good enough for DSP. The Raspberry Pie uses a fancier GPU and a simpler CPU (no DSP in the CPU). If you are compiling your own code with gcc, there are many options specific to the "neon" architecture. (It is on the TI website.) I've been doing some SDR on the Beagleboard XM, and the difference can be a factor of 3 in CPU utilization.
