Abstract
Apparatuses for data processing and methods of data processing are provided. A data processing apparatus performs data processing operations in response to a sequence of instructions including performing speculative execution of at least some of the sequence of instructions. In response to a branch instruction the data processing apparatus predicts whether or not the branch is taken or not taken further speculative instruction execution is based on that prediction. A path speculation cost is calculated in dependence on a number of recently flushed instructions and a rate at which speculatively executed instructions are issued may be modified based on the path speculation cost.
