Then you were under the wrong impression; it's the full Pentium instruction set architecture, right down to having the F00F Bug - which wasn't present on the 486. I can tell you that as an absolute certainty, 'cos I've got a Quark-based Galileo right 'ere.
Might be interesting. I'm after something that can handle FLAC and generate I²S signal. Right now the Beagle Bone Black is my best friend, but I'm not done searching for another viable solution .
The Edison's no good for you, then; it's more of a computer-on-module (CoM) than a single-board computer (SoC). Have you looked into a Raspberry Pi with a Wolfson Audio board attached?
I'm following this blog : http://hifiduino.wordpress.com/ They made an interresting comparison between Rpi and BBB : http://hifiduino.wordpress.com/2014/03/10/beaglebone-black-for-audio/ I have an antique (1963) Telefunken valve amp + valve radio tuner that I'm willing to modernize. The idea is to keep the antique look of it and add a network controlled media player. I need a µC with ethernet + I²S to access and read audio files (or web radios) and and I²S DAC to send analog signal to the preamp stage (ECC83). I've ordered two Ti/BurrBrown PCM1794A chip soldered onto an SSOP28 to DIP adaptor for the DAC purpose (one per channel).
