FPGAs (Field Programmable Gate Arrays) are semiconductor chips that can be reconfigured again and again to fit new needs. We talked with Chetan Khona, Director Industrial, Vision, Healthcare & Sciences at Xilinx, the company that literally invented the FPGA, about what they mean for IoT. Also featured: Raz Roditti of Razor Labs, an Israeli startup, on how to turn clunky heavy industrial machinery into state-of-the-art smart machines.
