Abstract
Method and apparatus for changing the sequential execution of instructions in a pipelined instruction processor by using a microcode controlled redirect controller. The execution of a redirect instruction by the pipelined instruction processor provides a number of microcode bits including a target address to the redirect controller, a predetermined combination of the microcode bits then causes the redirect controller to redirect the execution sequence of the instructions from the next sequential instruction to a target instruction.
