Circuit arrangement for e.g. battery supported mobile application, has evaluation circuits for evaluating variable that is provided for supply voltage of integrated circuit based on correction requirement of output value

摘要

The arrangement has a digital computing circuit (2) and a test circuit (3). The test circuit verifies an output value of the digital computing circuit on the basis of redundancy information. Evaluation circuits are arranged for evaluating a variable that is provided for a supply voltage of an integrated circuit based on correction requirement of the output value. The evaluation circuits comprise a statistics module. An independent claim is also included for a method for controlling power consumption in a digital computing circuit.
