Implementations§

source§

impl Btb

source

pub fn predict(self, _pc: u32) -> HOption<u32>

Returns the predicted target address of a JALR instruction with the given PC.

source

pub fn update(self, _pc: u32, _target: u32) -> Self

Returns the updated BTB when a target address misprediction occurs.

It updates the entry corresponding to the given PC with the given correct target address.
