Digital electronic adder and subtractor circuit of 5211 code - has adder and subtractor processing unit operated by signal generated by logic control circuit |
摘要 |
The circuit has a pair of input registers coupled to the inputs of an adder and subtractor (5) circuit. Coupled to the adder and subtractor stages is a control circuit that generates the necessary signals for operation. Outputs in 5211 code form are provided by a further shift register. The control circuit is based upon a pair of counters (17,19) generating control pulses for both the addition and subtraction cycles. A further stage (18) provides control of the decimal point. ADVANTAGE - Reduced number of logic devices.
