Patent ID: 8201011

Claim:
A method comprising: providing a plurality of blocks, each comprising a buffer with an input port configured to receive an input signal and an output port configured to convey an output signal corresponding to the input signal, wherein at least a first block of the plurality of blocks includes a buffer with a delay element which may or may not be utilized to generate the output signal corresponding to the input signal; receiving said input signal at the first block and a second block of the plurality of blocks, wherein the input signal is received by the first block at a first time, and the input signal is received by the second block at a second time; selecting use of the delay element in the first block in response to determining the first time is less than the second time by at least a first predetermined difference; selecting non-use of the delay element in the first block and selecting non-use of the delay element in the second block in response to determining the first time is not less than the second time by at least a second predetermined difference; and wherein selecting use of the delay element comprises selecting a first path which includes the delay element between the input port and the output port, and wherein selecting non-use of the delay element comprises selecting a second path which does not include the delay element.
