In Figure 2.9, 15:5 compressor architecture requires six full adder (FP1-FP6), two half adders (HP1-Hp2), and two 5:3 compressors (CP1-CP2). Working principle of 15:5 compressor is (IN1-IN3) inputs given to the full adder (FP1), (IN4-IN6) inputs given to the full adder (FP2), (IN7-IN9) inputs given to the full adder (FP3), inputs (IN10-IN12) are inputted to the FP4 and input (IN13-IN15) are inputted to the FP5. Output signal sum obtained from all these full adders (FP1), (FP2), (FP3), (FP4), and (FP5) is given to the 5:3 compressor (CP2) and carry is given to the 5:3 compressor (CP1). The sum obtained from the 5:3 compressor (CP2) is the output Y1 of the compressor. The carry1 of 5:3 compressor (CP2) and the sum of 5:3 compressor (C1) given to half adder (HP1). The sum obtained from half adder (HP1) taken as output Y2. The carry of this half adder (HP1), carry2 of 5:3 compressor (CP2) and carry1 of 5:3 compressor (CP1) given to full adder (FP6). The sum obtained from full adder (FP6) taken as output Y3. The carry of this full adder (FP6) and carry2 of 5:3 compressor (CP1) given to half adder (HP2). The sum which is obtained from half adder (HP2) is taken as output Y4 and carry is taken as output Y5.
