The first PYNQ-Z2 seminar with Adam Taylor was interesting.
SoC-based boards are gaining more and more popularity. And this is not surprising, because such a combination provides truly amazing opportunities compared to the "just" processor or "just" FPGA. On such SoCs, you can build systems that combine algorithmically complex tasks, support for network stacks, GUIs and other things that are easier to implement on the processor, and tasks that require hard real time, signal processing, image processing and other tasks that are convenient for implementation FPGA. Of course, for many tasks you can use simple FPGAs (possibly including the IP core of a processor like NIOS II or MicroBlaze in them), many tasks can be solved on a processor of sufficient power using real-time operating systems (such as RTEMS), but still, SoC are currently a very attractive option for solving many problems, both in professional fields and for hobbies.
Since I myself use simple FPGAs, this board really interested me. I look forward to the next seminars.
