A method, computer program product, and system are provided for controlling a clock distribution network. For example, an embodiment of the method can include programming a predetermined delay time into a plurality of processing elements and controlling an activation and de-activation of these processing elements in a sequence based on the predetermined delay time. The processing elements are located in a system incorporating the clock distribution network, where the predetermined delay time can be programmed in a control register of a clock gate control circuit residing in the processing element. Further, when controlling the activation and de-activation of the processing elements, this activity can be controlled with a state machine based on the system's mode of operation. In controlling the activation and de-activation of the processing elements, the method described above can not only control the effects of di/dt in the system but also shut off clock signals in the clock distribution network when idle, thus reducing dynamic power consumption. |
