6 COMMON FPGA MODULES
Working with an FPGA can feel like building with LEGO: you have a limited variety of small bricks at your disposal, but by stacking them elegantly, you can create amazingly complex designs. At the lowest level, you’re working with LUTs and flip-flops. At a slightly higher level, there are several basic building blocks that appear over and over again in FPGA designs, including multiplexers and demultiplexers, shift registers, and first in, first out (FIFO) and other types of memory.
Each of these elements is very common. In fact, it’s likely that one or more of them will be used in every single FPGA project you’ll ever ...
