Abstract: Computer and graphics processing elements, connected generally in series, form a pipeline. Circuit elements known as di/dt throttles are inserted within the pipeline at strategic locations where the potential exists for data flow to transition from an idle state to a maximum data processing rate. The di/dt throttles gently ramp the rate of data flow from idle to a typical level. Disproportionate current draw and the consequent voltage droop are thus avoided, allowing an increased frequency of operation to be realized.
