Well, my bad If I offense anyone, it wasn't my intention.
-> I wasn't thinking of dropping the possible use case with high speed / high density connector. But for DIY, Samtec connector, let's be frank, are just unusable (difficulty to buy them, to solder them, and pretty costly too). (When I got my parella, I have found only a breakout board for _one_ connector ... at $80).
a daughter board to use these connector could be one way, but not a daughter board at $80. For less than $3 I've got a board with an atmega328 and all theirs pins usable, I will not pay $200 to use only 2 connectors when the parallela board is cheaper
-> I wasn't thinking of covering all gpio of the fpga for the "arduino-like". . But to cover gpio which aren't already in used, and in sufficient quantity that you could use for just more than 2 standard usage.
Parallela 2 board (or the daughter board) could also present the specific io which aren't populate on the board (as the 2nd GigE, 2nd USB, ...)
-> Concerning the capacity of the zynq for filtering. I appreciate the zynq 7020 and found the idea superb, but there are some area which are already taken into use for the connection of the ram, of the arm and of the epiphany.
In addition, my point was'nt saying that the "zynq is bad we must offloading things" , but "the possibility to add ADC/DAC and/or DSP "cheaply" could be great for those who want".
My example wasn't to your liking, and perhaps not true (there are only one way to be sure
) , and I apologize for this.
