Hi, I have experience with Zynq 7020. The Processor is Cortex-A9 with up
to 800Mhz (usually 667MHz) If you take 7045 or 7100, you get up to 1GHz,
but then you to buy licence for developing FPGA. For 7020 Xilinx tool
chain is for free.
My guesses are, for an actual phone to few processing power, for 3d
acceleration, the FPGA may be too small. But for a geek phone, FPGA gets
you much freedom...
