1 MULTIPLE-SEQUENCE DETECTOR DLD Semester Project

2 Group Members  Muhammad Ammad Siddique (061)  Syed Muhammad Zain (117)

3 Introduction  Multiple-Sequence Detector to detect the following two 8-bit sequences:    Using D Flip-Flops  Moore FSM Design

4 Intoduction (Continued)  Total of 15 states  Therefore, 4 Flip-Flops needed  1 input  1 output

8 State Table

9 K-Maps and Equation Simplification  Resulting in the following equations:  D A =BC(A’D’x+Dx’)+AB’C’(D’x’+Dx)+AD’x(B’C+BC’) +ACDx’  D B =B’C(D’x’+A’Dx)+BC’(A’x’+AD’x)+A(B’CD’+Dx’)  D C =A’B’(CD’x+Dx’)+C’x’(A’D+AD’)+Bx(CD+AC’)+B x’(A’C’+AD’)+AB’C’D  D D =B’x(A’+AC’)+D(A’B+AC)+x(A’C’D’+ABC+AD)  y = AB(C+D)

10 Proteus Implementation  Screenshot at the instant when the sequence has been detected is on the next page.  Present State:  A=1  B=1  C=0  D=1  Output=1 (Hence, Correct Sequence Detected)
