  • Evaluating A+B=K conditions in constant time 

    Cortadella Fortuny, Jordi; Llaberia Griñó, José M. (Institute of Electrical and Electronics Engineers (IEEE), 1988)
    Conference report
    Open Access
    The authors consider a type of condition that can be evaluated without requiring a complete ALU (arithmetic logic unit) operation. The circuit that is presented detects the condition A+B=K (n-bit numbers) in constant time, ...
