ABSTRACT:
Automatic selective power and energy control of one or more processing elements matches a degree of parallelism to a monitored condition, in a highly parallel programmable data processor. For example, logic of the parallel processor detects when program operations (e.g. for a particular task or due to a detected temperature) require less than the full width of the data path. In response, the control logic automatically sets a mode of operation requiring a subset of the parallel processing capacity. At least one parallel processing element, that is not needed, can be shut down, to conserve energy and/or to reduce heating (i.e., power consumption). At a later time, when operation of the added capacity is appropriate, the logic detects the change in processing conditions and automatically sets the mode of operation to that of the wider data path, typically the full width. The mode change reactivates the previously shut-down processing element.
