Abstract: An integrated circuit comprises: a first processing stage comprising processing logic for performing a processing operation on an input signal to generate an output signal, wherein the input signal corresponds to an output signal of a previous processing stage; a first sampling element adapted to sample a first value of said output signal synchronously with a clock signal; a second sampling element adapted to sample a second value of said output signal synchronously with a first delayed clock signal; and a first delayed clock signal generator, adapted to selectively generate said first delayed clock signal in response to a control signal generated in said previous processing stage.

Abstract: An integrated circuit comprising a set of data processing units including a first data processing unit and at least one second data processing unit operable at variable frequencies is disclosed. The integrated circuit further includes an instruction scheduler adapted to evaluate data dependencies between individual instructions in a received plurality of instructions and assign the instructions to the first data processing unit and the at least one second data processing unit for parallel execution in accordance with said data dependencies. The integrated circuit is operable in a first power mode and a second power mode. The second power mode is a reduced power mode compared to the first power mode and is adapted to adjust the operating frequency of the first data processing unit and the at least one second data processing unit in the second power mode as a function of the evaluated data dependencies.
