ABSTRACT:
In the pipeline data processing system, a branch instruction is preliminarily detected from a string of instructions to be executed before execution thereof and the branch address is calculated. When the branch address is thereafter changed due to a change in the content of the register used to calculate the branch address, the calculated branch address is invalidated and a new branch address is calculated and the branch is executed. The change of the branch address is checked and performed on a basis of the comparison between the fields used for address calculation and the field of the address into which the data is to be written.
