[sdiy] $53 Intel Edison dual 500MHz Atom 1GB RAM SOC board has I2S

[Terry Shultz]

Hi Robin,

Are there any DSP Libs available for the INTEL ATOM?

We rejected it a few years back at GM due to the lack of any DSP Libs and the ARM platform Could use the iEEE 758 ? libs as a starting point.

My Memory on this is somewhat dated but it was a point of contention and Intel had already sold off their ARM business to Marvell I believe by that point.

Perhaps you have more current info and could illuminate this a bit further.

I presently use Sharc and Ti DSP and several TI device I am using have ARM 9 + DSP. 

DSP functions are not clear on this device but I2S is always welcome if they are not MUXed with other functions necessary.

This is yet another thing to look out for on some of the ARM devices as it seems Audio I/O is not as forefront as Video needs and other I/O ports used for Memory, Network etc.

Just my 2 cents.

best regards,

Terry
