Getting Started with FPGAs

9 USEFUL FPGA PRIMITIVES

So far, you’ve learned about the two most fundamental FPGA components: the LUT and the flip-flop. These general-purpose components are the main workhorses in your FPGA, but there are also other dedicated components that are commonly used in FPGA designs for more specialized tasks. These components are usually called primitives, but they’re also sometimes referred to as hard IP or cores.

Working with primitives helps you get the most out of your FPGA. In fact, a lot of modern FPGA development revolves around linking together these pre-existing primitives, with custom code added as needed for application-specific logic. ...
