Re: External Ethernet Microcontroller or ZYNQ
Obviously, the question can't be answered without considering the intended system purpose, data paths and processing.
You are presuming a FPGA, hence the data path is apparently between FPGA fabric and ethernet. For the"external microcontroller" variant, how's the data transported between FPGA and processor? The SoC (e.g. ZYNQ) advantage is the fast interface between FPGA fabric, processor core and hardwired peripherals.
