Abstract

PURPOSE: To realize the branching to the optional address via one branch order by storing the branch address information at the branch address memory part, thus reducing the execution time.
CONSTITUTION: The contents of the N address at address register part 3 is stored in order register 4 via the next clock CL. When this stored order is decided as the branch order at order decision part 5, contents B of the branch address information are stored into address register part 8. Then address A of the contents corresponding to the address is read out of branch address memory part 7, and this contents A are stored into address register part 3. Then the order of address A is sent to register 4 via the next clock. Thus the branching becomes possible to the optional address by one order.
