What is Task skipping?

Task skipping is an approximate computing technique that allows to skip code blocks according to a specific boolean condition to be checked at run-time.

This technique is usually applied on the most computational-intensive section of the code.

It relies on the fact that a tuple of values sequentially computed are going to be useful only if the whole tuple meet certain conditions. Knowing that a value of the tuple invalides or probably will invalidate the whole tuple, it is possible to avoid the computation of the rest of the tuple.
