1. x86 processors use little endian storage format for floating point representation.
2. In floating point representation, the digits to the left and the right of the ‘point’ are known as the integer part and fraction part respectively.
3. Exponent storage adds a bias to an exponent because they are stored unsigned integers.
4. Floats are single precision, which means the binary point is shifted until a single “1” is left of the point.
5. The FPU performs arithmetic using single precision format.
6. overflow is when a floating point result in computed beyond the valid range.
7. The FPU co-processor is denoted as overflow/underflow.
8. The FPU Control Register dedicates two bits for Enable/Disable rounding methods, meaning possible rounding methods exist.
9. The FPU register stack has 8 registers that are 80 bits wide.
10. Streaming SIMD Extensions allow for single instructions operate on multiple data.
11. MMX technology introduced 4 datatypes. (Packed byte, Packed word, Packed doubleword, Quadword)
12. Advanced Vector Extensions have added XMM (128-bit) and YMM (256-bit) register.
13. AVX allows for three operand instructions.
