Using Multi Bit Flip Flops Achieving Reduced Area
نویسنده
چکیده
A UART (Universal Asynchronous Receiver and Transmitter) is a device allowing the reception and transmission of information, in a serial and asynchronous way. This project focuses on the implementation of UART with status register using multi bit flip-flop and comparing it with UART with status register using single bit flip-flops. During the reception of data, status register indicates parity error, framing error, overrun error and break error. The multi bit flip-flop is indicated in this status register. In modern very large scale integrated circuits, Power reduction and area reduction has become a vital design goal for sophisticated design applications. So in this project the power consumed and area occupied by both multi-bit flip-flop and single bit flip is compared. The underlying idea behind multi-bit flip-flop method is to eliminate total inverter number by sharing the inverters in the flip-flops. Based on the elimination feature of redundant inverters in merging single bit flip-flops into multi bit flip-flops, gives reduction of wired length and this result in reduction of power consumption and area.

-This paper proposes a low-power and area-efficient shift register using digital pulsed latches. The area and power consumption are reduced by replacing flip-flops with pulsed latches. This method solves the timing problem between pulsed latches through the use of multiple non-overlap delayed pulsed clock signals instead of the conventional single pulsed clock signal. The shift register uses a ...
