In the following circuit, the 3 bit up-counter counts from Q2Q1Q0-000 to Q₂Q₁Q0= 111. Q2 is the most significant bit and Qo is the least significant bit. Assuming the 3-bit up-counter is initialized to be Q₂Q1Q0-000. The 3-to-8 decoder has output C, which has 8 bits, and is specified as C7 C6 C5 C4 C3 C2 C1 Co (Co is the least significant bit). Which statements below correctly describe the circuit? Choose all that apply. clock С7 С6 С5 С4 С3 С2 С1 С0 3 to 8 decoder Q2 Q1Q0 3 bit up-counter
In single precision (IEEE-754 standard), 8 bits are used for storing the exponent (the bias is 127), and 23 bits are used for storing the mantissa. (a) What are the smallest and the largest positive numbers that can be stored in single precision? (b) What is the smallest value of the mantissa that can be stored?
4 bit 2’s Complement Multiplier INPUT A: 4 bit 2’s Complement numberINPUT B: 4 bit 2’s Complement numberOUTPUT: the product of A x B represented as a 8 bit 2’s Complement number You are only allowed to use the basic gates: NOT, AND, OR, XOR. You may however, use these basic gates to build your own custom circuits (i.e. Adder). You are NOT ALLOWED to use Logisim’s built in circuits. Each custom circuit is to be implemented as a sub-circuit as discussed in class.
