Abstract: In this paper I propose the design and implementation of first in first out shift register based on multi bit flip flop for universal asynchronous receiver and transmitter (UART).UART is a major communication component to interface the microcontroller with the external modules like GSM, GPS etc. One of the problems in embedded systems is the time consuming by the external devices to communicate with the controlling device. Here we are concentrating mainly on fast communication among the devices in embedded applications. Simulation results have been shown that the proposed system is 50% faster than the existing system. Code is written in VHDL and modeled in Xilinx 10.1 ISE, implemented with FPGA Spartan 3E hardware tool.
