Hi, well I played a bit with @home things a while ago when it was new, and didn't read through the whole thread, sorry to say. If I'm not mistaken it is observed that the PI core to Zinq core improvement is only 1:1.3 ?! That I hope is due to not great compiled and /or optimized software, and without NEON, because NEON should make quite a difference I would think ?
Well, there are (for those who know a bit about the Xilinx or other brand programmable logic) IP "blocks" for the FPGA too, which compute FFTs, usually not too many bits, but the FPGA structure and the DSP mul/add power should make a difference too.
It may just boil down to which savvy programmer+ architecture buff sees the time and effect as worth while to squeeze some real juice out of the modern processors architectures!
