Up-conversion

Optimising the conversion

A number of different optimisation techniques were tried before a final implementation was decided on. Usually the quickest way to speed up the execution of code is to reduce the number of arithmetic operations and simplify those that cannot be removed. However, with this code the arithmetic was not the main performance factor and IO issues took centre stage. In each of the following three sections I will describe an area that should be considered when optimising software before describing how this is achieved in the optimised code.
