A comparator is any circuit whose output will assert when an input signal rises above a given threshold, and de-assert when the input falls back below the threshold.

In this project, we will design the arithmetic circuits in FPGA. We will build a 4-bit magnitude comparators, a ripple-carry adder, and a multiplier circuit. You can challenge yourself by integrating all those circuits together with some multiplexer to build an arithmetic logic unit (ALU).

In this design, you are going to be asked to do a VGA Controller to display something on your monitor. Actually, VGA controller is a quite simple design which only requires two counters and several comparators.

When designing circuits with bussed inputs that represent binary numbers, it is often easier to consider a circuit designed for a single pair of bits, rather than for the entire binary number. This method of analysis is called Bit-Slice.
