Static prediction is the simplest branch prediction technique because it does not rely on information about the dynamic history of code executing. Instead, it predicts the outcome of a branch based solely on the branch instruction. The early implementations of SPARC and MIPS (two of the first commercial RISC architectures) used single-direction static branch prediction: they always predi… Web20 unified with branch prediction 2000 180 nm 2002 NetBurst (Pentium 4) (Northwood, Gallatin) 3466 130 nm ... timers, and chip select logic.
