An MISD machine is exemplified by a systolic array, which is a type of array. A systolic array is a network of data processing units that is organised as a pipeline network or "wavefront." Each of these elements does not require the use of a programme counter because execution is initiated by the arrival of new data. Clocked systolic arrays compute in "lock-step," with each unit completing alternate computation and communication stages on a single clock cycle.
