You are spot on DLC86. I am getting a lot of expected heat yet no facts to back up opposing views.Something is not clear though. The SC-587 the original FM9 uses has 500 MHz DSP cores and a 450 MHz ARM core, the only slightly more powerful Sharc+ chip I can see on Analog Devices site is the SC-589 which has a 500 MHz ARM core but still the same 500 MHz DSP cores.
Afaik the ARM core is not used for audio processing in the FM3/9 so using that chip shouldn't produce a 10% performance boost. Maybe it's a chip from an entirely different manufacturer?
Or maybe just one of the new 1 GHz dual core chips? Even though these seems to not be available anywhere yet and I would expect a more significant performance increase from these.
