9-bit code converter from binary radix-2 to BCD |
|||
|
|
|||||
1. Specifications
Large code converters such as radix-2 --> BCD (Bin_BCD_9bit) can be implemented using hierarchical schematics from 74184/74185 datasheet. Implement a 9-bit code converter from binary radix-2 to BCD using plan C2. The basic expandable component is the DM74185.
The same project B3.16 is proposed in Chapter 3 for learning the basics of μC software organisation and basic digital I/O.

Draw the circuit truth table and an example of timing diagram to be used in section 4 for testing the device.
2. Planning
Adapt the 9-bit hierarchical block from the datasheet to our style and translate it to VHDL.
Using plan A: equations.
