If you need to convert many numbers back-to-back at high speeds, a pipelined design is best. We split the iterations across multiple stages.
For wide inputs (>16 bits), the combinational version may cause long paths. Pipelining or sequential version is safer. Binary To Bcd Verilog Code
To adapt the sequential code:
The algorithm converts an n‑bit binary number into a BCD number by iteratively shifting bits from the binary input into a BCD shift register, with correction logic applied after each shift. If you need to convert many numbers back-to-back
The binary to BCD conversion process involves several steps: Binary To Bcd Verilog Code
