"In computer architecture, predication is a feature that provides an alternative to conditional transfer of control, as implemented by conditional branch machine instructions. Predication works by having conditional (predicated) non-branch instructions associated with a predicate, a Boolean value used by … See more Most computer programs contain conditional code, which will be executed only under specific conditions depending on factors that cannot be determined beforehand, for example depending on user input. As the majority of See more Predication's primary drawback is in increased encoding space.

If it is not, the microcontroller will continue to the next instruction. Jumping is a form of Unconditional Braching. It redirects program flow regardless of conditions.

WebMay 23, 2024 · The penalty for a branch is (a) latency to resolve the branch and (b) latency to fetch the next instruction. The compiler will use predication if it is cheaper than the above two costs. This is usually 6-10 instructions. If the branch is multi-way divergent there is higher cost as the branch (BRX) will have to be executed multiple times.
