Branch prediction

What is branch prediction?
Branch prediction is an approach to computer architecture that seeks to reduce the cost of branching. Branch prediction speeds branch instruction processing with CPUs that use pipelining. The technique only involves executing certain statements when certain predicates are true. Branch prediction is typically implemented in hardware using a branch predictor.

Branch prediction is also known as branch prediction or simply prediction.

Branch prediction is a technique used to speed the execution of instructions on processors that use pipelining. The CPUs initially executed instructions one by one as they came in, but the introduction of pipelining meant that branch instructions could slow the processor down significantly as the processor had to wait for the conditional jump to complete.

Branch prediction breaks statements into predicates, much like predicate logic. A CPU using branch prediction will only execute instructions when a predicate is true. One example is the use of conditional logic. Because there is no unnecessary code running, the processor can work much more efficiently. Branch prediction is implemented in CPU logic with a branch predictor.
