1. Specifications

Large code converters such as a 3-digit BCD to binary radix-2 (BCD_bin_3digit) can be implemented using hierarchical schematics extracted from 74184/74185 datasheet.

Symbol and truth table

Implement a 3-digit code converter from BCD to binary radix-2 using plan C2. The basic expandable component is the DM74184 chip that we can translate to VHDL. For example, in this tutorial project we designed the BCD_bin_mod40 component.
