 A mandelbrot set is a set of complex numbers that satisfy a certain mathematical property. The set is defined by iterating a function on a complex number, and checking if the result of the iteration is bounded. If the result is bounded, the complex number is part of the mandelbrot set. If the result is unbounded, the complex number is not part of the mandelbrot set.
 
 This project calculates the function `z = z^2 + c` iteratively, where `z` and `c` are complex numbers. The function is iterated on
-every clock cycle, and the result is checked to see if it is bounded (`|z| <= 2`). When the result is unbounded, the `unbounded` signal is set high.

 All the calculations are done in 32-bit IEEE 754 floating point format. The floating point addition code is taken from [Caravel FPU](https://github.dev/Lampro-Mellon/Caravel_FPU/blob/main/verilog/rtl/add_sub.sv), and the floating point multiplication code was generated by GPT-4o.

 The values of `Cr` and `Ci` are buffered, so you can load new values into the registers while the design is calculating the mandelbrot set for the previous values. When you strobe the `start` signal, the design will begin calculating the mandelbrot set for the new values of `c`.
 
+The following example illustrates how to load the value `c = 1.2 + 1.4i` into the registers and start the calculation:

+- 0x3F99999A is the IEEE 754 floating point representation of the real part of `c` (1.2)
+- 0x3FB33333 is the IEEE 754 floating point representation of the imaginary part of `c` (1.4)
+- Unbounded goes high two clock cycles after the start signal is strobed, indicating that the result is unbounded.

+When the calculation concludes, the `iter` signal will hold the number of iterations it took for the result to become unbounded. The `iter` signal is valid when the `unbounded` signal is set high.
