Xilinx Risc-V Board Tutorial : Hexadecimal Number to BCD Code Conversion and Application – FII-PRX100 FPGA Board Experiment 8

SteveGuys

Experiment 8 Hexadecimal Number to BCD Code Conversion and Application 1.Experiment Objective Since the hexadecimal display is not intuitive, decimal display is more widely used in real life. Human eye recognition is relatively slow, so the display from hexadecimal to decimal does not need to be too fast. Generally, there are two methods Countdown method: Under the control of the synchronous clock, the hexadecimal number is decremented by 1 until it is reduced to 0. At the same time, the appropriate BCD code decimal counter is designed to increment. When…
