Grocery stores now-a-days are crowded almost every hour of the day resulting in long queues at every billing counter. This paper is to develop an automated self-billing system that would save the customers’ time and would also be economic enough to be smoothly implemented. The authors propose the use of RFID technology and an Arduino ...

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 ...
