चरण 1: आपल्याला प्रत्येक चार-बिट गटांसोबत 0011 जोडून संख्या (जे जोडायचे आहेत) अतिरिक्त-3 मध्ये रूपांतरित करावे लागतील.
चरण 2: आता बायनरी जोडण्याचे मूलभूत नियम वापरून संख्या जोडल्या जातात.
चरण 3: आता, चार-बिट गटांपैकी कोणत्याही गटाने कॅरी तयार केली असेल, आम्हाला त्यांच्यासोबत 0011 जोडावे लागेल आणि जोडताना कॅरी तयार न केलेल्या गटांमधून 0011 वजा करावे लागेल.
चरण 4: या ऑपरेशननंतर आपल्याला मिळालेला निकाल अतिरिक्त-3 स्वरूपामध्ये आहे
उदाहरण: (1)10 + (4)10 = (5)10
XS - 3: 0100 + 0111 = 1011 = (11)
परंतु (5)10 साठी XS-3 1000 असल्याने आपल्याला 1000 मिळतील.
तर, आपल्याला निकालातून 3 वजा करणे आवश्यक आहे
उदा: (6)10 + (7)10 = (13)10
XS-33 मध्ये: 1001 + 1010 = 10011
परंतु आपल्याला 0100 0110 मिळणे अपेक्षित आहे
म्हणून आपल्याला निकालात 011 जोडणे आवश्यक आहे.
4-बिट XS-3 अॅडर :
जर C4 = 1, तर निकालात तीन जोडा (S3 S2 S1 S0)
C4 = 0 असल्यास, परिणामातून तीन (0011) वजा करा म्हणजेच 2 च्या तीन (1101) ची पूरक जोडली जाईल.
∴ दोन 4-बिट समांतर अॅडर आवश्यक आहेत.
