Binary IncrementerThe increment microoperation adds one binary value to the value of binary variables stored in a register. For instance, a 4bit register has a binary value 0110, when incremented by one the value becomes 0111. The increment microoperation is best implemented by a 4bit combinational circuit incrementer. A 4bit combinational circuit incrementer can be represented by the following block diagram.
Note: The 4bit binary incrementer circuit can be extended to an nbit binary incrementer by extending the circuit to include n halfadders. The least significant bit must have one input connected to logic1. The other inputs receive the number to be incremented or the carry from the previous stage.
