Abstract (en)

[origin: WO2005043299A2] The invention is a system for modifying the processing period in a digital logic module. The invention comprises the following. A processing circuit is configured to receive an input in order to create an output. A controller is coupled to the processing circuit and is configured to track L manipulations, wherein L is an integer. The controller is further configured to send a select signal to the processing circuit and to cause the processing circuit to manipulate the input over N clock cycles. N is an integer and N is less than or equal to L. N varies over the plurality of processing time periods. An output port is coupled to the processing circuit and is configured to convey the output.
