🔢 BCD Fundamentals
Binary Coded Decimal (BCD) is a binary encoding where each decimal digit is represented by a fixed-length binary sequence, typically 4 bits.
- Each decimal digit (0-9) uses exactly 4 bits
- 0 = 0000, 1 = 0001, 2 = 0010, ..., 9 = 1001
- BCD addition requires special correction for sums > 9
- Add 6 (0110) when a digit sum exceeds 9 or generates carry
- Widely used in digital systems and calculators
- Easier decimal-binary conversion than pure binary
💡 Practical Examples
Understanding BCD addition through real-world examples helps grasp the correction process and carry propagation.
- Simple Addition: 25 + 37 = 62 (no correction needed)
- With Correction: 29 + 17 = 46 (correction required for digit sum > 9)
- Multiple Carries: 99 + 99 = 198 (cascading corrections)
- Digital Clocks: Time calculations in BCD format
- Financial Systems: Precise decimal arithmetic
- Embedded Systems: Microcontroller applications
