You are to design a circuit that converts a four-bit binary number V=v3v2v1v0into its two-digit decimal equiv-alent D=d1d0.Table1shows the required output values.A partial design of this circuit is given in Figure1.It includes a comparator that checks when the value of V is greater...

Step1: shift the binary number left one bit to BCD number (LSB).Step2: every four bits of BCD number from the LSB present one bit of decimal number, if the binary value in any of 4-bit BCD columns is greater than 4, add 3 to the value in that BCD column.Step3: if ...
Convert Binary to BCD Binary Coded Decimal (BCD) is used to display digits on a 7-Segment display, but internal signals in an FPGA use binary. This module converts binary to BCD using a double-dabbler. What is a FIFO? Learn the basics of a FIFO. There are two simple rules governing ...
Here's a little table showing how to double each bit in BCD. All numbers shown are decimal. input tens units result 0 0 0 0 1 0 2 2 2 0 4 4 3 0 6 6 4 0 8 8 5 1 0 10 6 1 2 12 7 1 4 14 8 1 6 16 9 1 8 18The tens column thus represents an overflow into the...
