ABSTRACT:
The decoding of certain instructions cause an instruction unit of a production line data processing system to stall. Instructions still in the production line are executed, but no new instructions are sent into the production line until the instruction that caused the stall condition is executed. The execution of the instruction that caused the stall is completed by an execution unit taking over control of an address unit.
