What should I do if the algorithm overhead cannot meet the customer's requirements?

1. As many approximate calculations
as possible. For example, in a computer, the cost of multiplication and division is far greater than addition and subtraction. Then we can perform approximate calculations similar to the following figure
Insert picture description here

2. Try to use LUT lookup table as much as possible

3. Threshold calculation

4. Minimize unnecessary CPU calculations, such as reducing floating point calculations

5. See if there is any pre-calculation or approximate calculation when deriving the mathematical formula
