You are using a signed 8-bit ALU to do the following arithmetic operations. Assume two numbers in binary are, a = (0110 1111)2 and b = (0110 0100)2. 6+4+5=15 (i) C = a + b (ii) D = a - b

could you help me with question d) pls thanks

A) How many Binary digits do you need to represent a deciaml number 355?

show how to design a 8-bit Function Unit Combining Arithmetic Logic Unit (ALU) and a Shifter that can perform the operations given in table 1 below. Use X and Y as 8 bits input and F as 8 bits output as shown in Figure 1. S0,S1,S2 and S3 represent the selction code in the operation set table Three statue bits V (over flow), C (carry), N (negative) and are related to arrithmatic operations and statue bit Z (zero) is relataed to both arrithmatic and logic operation. Test your designed Function Unit with necessary tables.

The 3-bit shift register is shifted five times to the right with the serial input being 1011101. What is the content of the register? (Write your answer using only 0s and/or 1s.)

20. Suppose we have just found yet another representation for floating point numbers. Using this representation, a li2-bit floating point number has 1 bit for the sign of the number, 4 bits for the exponent and 7 bits for the mantissa, which is normalized as in the Simple Model so that the first digit to the right of the radix points must be a 1. Numbers in the exponent are in signed 2's complement representation. No bias is used and there are no implied bits. Show the representation for the smallest positive number this machine can represent using the following format (simply fill in the squares provided). What decimal number does this equate to? : SIGN EXPONENT MANTISSA

How to do it?

a) Convert the Decimal number (21.22)10 to binary number b) Convert the binary number (10.011)2 to Decimal number c) Perform the following subtractions using two’s complement arithmetic: X − Y = 1011100 − 1110010 X − Y = 10101111 – 01110011     Please answer all subpart either dislike is ready please Clean handwriting

Using excess-15 notation, find the decimal equivalent of this binary number 0011101100000000.

What is the value for the 32-bit register EAX after executing the mnemonic opcode/operand instruction MOVZX? (This mnemonic opcode/operand instruction converts 8-bits to 32-bits) MOV EAX, 0 MOV AX, 0X54C9BF5 MOVZX EAX, AX EAX= 004C9BF5 а. EAX= 000C9BF5 b. EAX= 000000F5 EAX= 00009BF5 O d.
