Digital data processing circuit with control of data flow by control of the supply voltage

摘要

Digital data processing electronic circuitry based on self-timed elements. The operating speed of the electronic circuitry is determined by its power supply voltage. Moreover, a buffer is connected either to the input or to the output of the electronic circuitry. A filling degree signal from the buffer is fed back to a control input of a power supply voltage controller for the electronic circuitry. In this way the supply voltage of the electronic circuitry is adjusted to control the data flow in such a way that the buffer tends not to fill up or to become empty.
