Q6 Figure Q6 shows a functional block diagram of a custom processor and the Register Transfer Level (RTL) codes to perform one of the processor operations. Assume that signal p and q are never '1' simultaneously. The ALU operation is given in Table Q6. SO: () S1: (p) / R1+ 2; / R2 + R1; R1 R2 (p) / R2 + R1; / R1+ R1 + R2; (pq) / R2 0; / R2 + 2R1; / R2 + R1– R2; S2: (p) S3: (р) (q) / done = 1; / goto SO; () B ALU_op Figure Q6 Table Q6 ALUop [1:0] 00 01 Operation A +B А -В Complement B Pass B 10 11
