![]() This is a four bit shift register and therefore consists of four D flip-flops. Shift registers consist of D flip-flops as shown in the figure below. A shift register has the capability of shifting the data stored in the register from left to right or right to left. Shift Register Operation A register stores data i.e. ![]() Two different ways to code a shift register in VHDL are shown. Shift_reg(3) 3) shift_reg(1) shift register bits to the LEDs LED.Ī shift register is written in VHDL and implemented on a Xilinx CPLD. The image below shows an eight bit shift register that is created in VHDL code in this tutorial. ![]() Serial Adder Moore FSM: Control Circuit for Automatic Door.
