Apparatus and method of determining power of base values used in vehicle applications

An apparatus for calculating a power of, the apparatus comprising:

• an interface with an input and output, the interface configured to receive a signal at the input representing a numerical value from a vehicular application;
• a memory including and having stored therein a look-up table;
• a processor coupled to the interface and the memory, the processor configured to calculate a power value, the power value being a predetermined base raised to the power of the numerical value, the calculation using at least some multiplication and shifting operations, the calculation further accessing the look-up table stored in a memory, the processor further configured to return the calculated power value to the vehicular application at the output;
• wherein at the vehicular application, the calculated power value is utilized in a calculation and a result of the calculation is obtained and wherein a parameter of the vehicular application according to the result is altered.

A computer usable medium having a computer readable program code embodied therein, said computer readable program code adapted to be executed to implement a method of of calculating a power value, the method comprising:

• receiving a signal representing a numerical value from a vehicular application;
• calculating a power value, the power value being a predetermined base raised to the power of the numerical value, the calculating using at least some multiplication and shifting operations, the calculating further accessing a look-up table stored in a memory;
• returning the calculated power value to the vehicular application;
• at the vehicular application, utilizing the calculated power value in a calculation and obtaining a result of the calculation;
• altering a parameter of the vehicular application according to the result.
