In this tutorial, we will learn about the N-bit Parallel Adders (4-bit Binary adders and Subtractors) in Digital Electronics.
作者: MH Weik 摘要: A digital adder that concurrently adds both the digits in all the corresponding digit positions of the augend and addend at one time, developing a partial sum and a partial carry, if any, storing... DOI: 10.1007/1-4020-0613-6_13602 年份: 2000 收藏...
andParallel Subtractor, which can be designed in two ways. For optimization, it’s better to use a single circuit for multiple operations. So, we need to consider if we can perform both n-bit addition and subtraction with one digital circuit—aparallel adder or subtractor. ...
ADDERS (Digital electronics)SUMMING circuitsARITHMETICELECTRIC power consumptionRELAY control systemsIn this brief, various multi-operand parallel prefix adders are designed and they are implemented in fused multiply-accumulate (MAC) unit. A multi-operand adder is the fascinating technique in contrast with...

While this second multiplication is being performed, the partial product and carry bits from the first multiplication are being shifted out of the shift registers to an adder which combines these bits to derive the final product bits. Multiple multiplicand storage registers are provided for allowing...
