TI Mixes ARM cores with DSPs and programmable logic

This is additional information that what I suspected was happening, is, which is that the combination of some hard "cores" + FPGA fabric is becoming useful. The original Xilinx run at this used Power PC cores but the current stuff (Zync) using ARM cores has had much better traction.

Looking at the TI site they want $328 each[1] in singles, not a great price point but not horrible given their performance but I don't think it crosses into the 'revolutionary' category.

That said, one of these and a couple of those 4 GSPS 12-bit ADC's and you'd have a pretty sweet front end for an oscilloscope. My new 200Mhz scope only has 2.5GSPS front ends on it and it cost $6K.

[1] This compares to $60 for singles of the Zync chip.

Tiny correction: Xilinx' combination ARM+FPGA SoC is called the Zynq (http://www.xilinx.com/products/silicon-devices/soc/zynq-7000...). This latest device from TI seems to be way higher-end than the Zynq (not surprising, since it's also newer).

Thanks, I am not a fan of phonetically obscured names :-). Xilinx's first foray into this space was the upper end Virtex series (the Virtex 4 and Virtex 5), I went back and looked at the pitch they gave me in 2005 around this. So here we are 10 years later and it seems like this stuff is finally getting closer to mainstream.
