Abstract
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.
