Conversion of binary to decimal numbers is often needed in firmware. And it’s done easily enough if multiplication and division by ten are acceptable.

For applications not requiring fast conversion,a single circuit that can performboth conversions proves adequate. Onesuch circuit (Figure 1 ) utilizes up/downcounters to obtain the desired results.
