A pipelined data processing system has an instruction set containing a stall instruction, and includes a plurality of stages and a pipeline controller for controlling execution and stall of a pipeline operation. The pipeline controller is configured to put the stages into a "frozen" condition on the basis of a stall signal generated by execution of the stall instruction, and to return the stages from the "frozen" condition to a "run" condition on the basis of an output pulse generated by a timer designated by an operand part of the stall instruction. <IMAGE> |
