The invention has several advantages over the previous implementations of a crossbar and barrel shifter in an interface receiver. Implementing the crossbar and barrel shifters using MAC blocks rather than logic elements reduces the number of logic elements by over one-half. For a word-wide data ...
and must face an increasing fan-out as they are closer to the output of the decoder. For instance, bit0and1have a fan-out of only 4 AND gates, while bit7has a fan-out of 256 AND gates (one half of them pertaining to the normal form and the other half to the complemented form)...
