Serial-parallel multipliers

Digital filters and other signal processing applications often involve a large number of multiplications. For many of these applications, the algorithm is sufficiently parallel that an implementation with many serial-parallel multipliers may be more efficient than implementation that uses a few parallel multipliers. This paper examines the design of several serial-parallel multipliers, compares and contrasts the different characteristics and improvements made on these multipliers. Comparison is also made between serial and parallel multipliers to give a rough estimate of the size versus speed trade off for using serial-parallel multipliers
