High speed and low power MAC unit is utmost requirement of today's VLSI systems and digital signal processing applications like FFT, finite impulse response filters, convolution etc. In this paper, the authors have discussed different types of multipliers like booth multiplier, combinational multiplier, Wallace tree multiplier, array multiplier and sequential multiplier. Each multiplier has its own advantages and disadvantages. Different types of techniques are presented for improving the speed and low power consumption like pipelined booth multiplication technique in which pipelining is used in booth multiplier to reduce the delay of each stage.
