Coding of unquantized spectrum sub-bands in superwideband audio codecs
We present several new methods for coding of spectrum coefficients in embedded audio codecs. In audio codecs, the spectrum is often divided in sub-bands, and quantized using a vec...

A2BC: Adaptive Address Bus Coding for Low Power Deep Sub-Micron Designs
Due to larger buses (length, width) and deep sub-micron effects where coupling capacitances between bus lines are in the same order of magnitude as base capacitances, power consum...
