In single cycle CPU, for the instruction lw $50, 8($t3), the output of the ALU will be O a. $50 O b. $50+$(t3) O c. 8 + $t3 O d. 8 + $50 In designing the 32-bit ALU, the set output of the last 1-bit ALU is connected to the - input of the first 1-bit ALU O a. less O b. Cin, O c. Cout O d. set We have an underflow in FP arithmetic if the exponent is less than O a. 127 O b. -126 O c. 128 O d. -127 O e. 126
