Pre-compute CASE condition and IF THEN ELSE conditions and jump into the right branch right away.
预先计算CASE条件和IF THEN ELSE条件，并立即跳至适当的分支。

This means that you either need to pre-compute them by hand (which is wasteful of your time) or build them at runtime (which is wasteful of the user's time).
这意味着可能需要手工提前计算好(这会浪费很多时间)，也可以在运行时构建(这会浪费用户的时间)。

The results of the experiment using this arithmetic to construct CL multi-wavelet pre-filter show that not only the compute speed is fast, but also the stability is remarkable improved.
