“The field programmable gate array (FPGA) has traditionally resided in the world of high-end professional development. Until recently, FPGAs stayed almost exclusively in that arena because of the high initial cost to purchase, the expense of the development tools, and the mystery surrounding the concept. Luckily, in recent years, much of that’s changed. There are now quite a few reasonably priced and easy to use FPGA development boards, and the basic tools can often be downloaded for free. A few of these boards were noted in a previous article: “The Best FPGA Development Board for New Designers.””
