Abstract
A conversion apparatus for quantizing a set of weights for a weighted sum signal processing system, including a predetermined number of conversion arrays operable in succession and a transfer and monitor circuit. Each conversion array stores a plurality of values to be converted, quantizes the values to be converted to produce a set of discrete values and a set of error values and replaces the contents of the means for storing with the set of discrete values. Each conversion array also combines the set of error values with a set of interpolator weights to form a transformed error set. The transfer and monitor circuit successively combines the transformed error set most recently formed with the contents of a successive conversion array, monitors the successively produced sets of error values, and halts the successive conversions and combinations when a predetermined condition is satisfied. The invention also features a method of quantizing such a set of weights.
