Abstract

See full text

A computing circuit that includes clocked circuitry, a controller, and a clock generator. The clocked circuitry is configured to receive data and to perform data manipulation on the data based on a first clock signal. The controller is configured to control the transmission of the data to the clocked circuitry. The clock generator is configured to receive as inputs a second clock signal and a delay control signal from the controller, and to delay the second clock signal to generate the first clock signal. The clock generator includes a main delay component configured to receive the second clock signal and to output the first clock signal. The clock generator also includes a switchable delay component connected in parallel with the main delay component, where the switchable delay component is configured to receive as an input the delay control signal from the controller.
