Unformatted text preview: EE200 DIGITAL LOGIC CIRCUIT DESIGN Class Notes CLASS 13-3 The material covered in this lecture will be as follows: ⇒ Serial addition. ⇒ Universal shift register. After finishing this lecture, you should be able to: ⇒ Describe the main functions of registers and counters. ⇒ Differentiate between shift registers and registers with parallel load. ⇒ Understand the serial transfer operation in registers. ⇒ Understand the operation of the universal shift register. erial Addition S We are going to investigate the operation of a serial adder in omparison to the parallel adder. c The two binary numbers to be added serially are stored in shift registers A and B. The carry of the full adder is stored in a D flip- flop and used as the carry-in with the next pair of bits to be added. The sum bit is shifted in shift register A to replace the first number. At the end of the number of clock pulses used to add the two numbers, the sum will be available in register A. Register B can be made to contain a third number to be added to the sum....
