Perhaps it will be helpful to keep track of what chipsets are used where.
I believe Acurus uses a Texas Instruments chipset while the other ≥16 channel SSPs use Analog Devices SHARC DSPs.
In my quest to reverse engineer some of these SSPs' ADI DSPs I have revised this listing many times. (Now I wish I had visited ADI at 2017 CEDIA!) These ADI press releases give the best info:
4th Gen SHARC
4th-Gen Data Sheet PDF
Based on their data-sheet, Storm Audio is using 2 4th gen SHARCs with either the ADSP-21486s
being the most likely decoder.
Based on their white-paper, Lyngdorf is using 8 (!) 4th gen SHARCs with the ADSP-21486s
the most likely decoder.
Datasat Atmos expansion: 1x ADI SHARC ADSP-21487
(decoder), 2x ADSP-21489
Datasat 4XLR expansion DSP?
5th Gen SHARC+
5th-Gen Daya Sheet PDF
Emotiva is using 2x ADSP-SC573 SHARC DSP chips
(gen5). 2 ARMs and 4 SHARC+ cores!
One thing that sticks out to me is ADI's mention of code compatibility between generations of the SHARC family of processors. It will be interesting to see how this all develops (or doesn't) over the next year. 9.1.6 for all (Datasat, Emotiva, Lyngdorf, and Storm) would be a win-win-win-win!
