Bit-serial Digital Signal Processing Using Multiple Operand Addition
BA Swanson · 1987
Many common DSP tasks can be formulated in terms of multiple-operand addition, allowing the use of column-sum (i.e. carry-save) techniques. In bit-serial form, performance superior to word-wide DSP microprocessors can then be achieved. A novel pass transistor implementation of the required (p,q) parallel counters consumes less power and area than previous schemes.
