Analysis

Three items:

1. Create 16 32-bit registers to hold floating point numbers.
2. Create new instructions for addition, subtraction, multiply, and divide operations.
   2.1 Immediate parameters are considered unsigned integers.
   2.2 The Floating Point IP will be used.
3. Create new instructions for loading, storing, and converting to/from integer and floating point.

New operation instructions opcodes as integer add, subtract, multiply, and divide but with the flag set to 1.
