**Understanding Bitwise Operations for an 8-bit Operand**When working with an 8-bit operand, specific operations can be performed using an 8-bit mask and a logical operator. The bit positions in the operand are numbered from 7 to 0, left to right. Below are examples of some operations and the corresponding logical operators and masks required.**a. Setting all bits to 1:**To set every bit in an 8-bit operand to 1, a logical OR or SET operation is typically used with a mask of 1s.- **Logical Operator:** OR- **Logical Mask:** 1111 1111 **b. Clearing bits 5, 4, 3, and 2 to 0:**To clear bits 5, 4, 3, and 2, a logical AND operation is used with a mask that has 0s at positions 5, 4, 3, and 2.- **Logical Operator:** AND- **Logical Mask:** 1100 0011 **c. Complementing bits 2, 1, and 0:**To flip the bits 2, 1, and 0 (complement operation), a logical XOR operation is used with a mask that has 1s at positions 2, 1, and 0.- **Logical Operator:** XOR- **Logical Mask:** 0000 0111 **d. Setting bits 7, 6, and 5 to 1:**To set bits 7, 6, and 5 to 1 without affecting other bits, a logical OR operation is used with a mask that has 1s at positions 7, 6, and 5.- **Logical Operator:** OR- **Logical Mask:** 1110 0000 These bitwise operations allow for precise control over individual bits within an 8-bit operand, enabling various data manipulation tasks in computing and digital communication.

A logical operator is a symbol or keyword used to perform operations on one or more logical values…

6. For an 8-bit operand, specify the 8-bit mask and the logical operator to perform the following operations. Bit positions are numbered 7-0, left to right. a. Logical Operator: Logical Mask: b. Set all bits to 1. Logical Operator: C. Clear bits 5, 4, 3, and 2 to 0. All other bits remain unchanged. Logical Mask: d. Complement bits 2, 1, and O. All other bits remain unchanged. Logical Operator: Logical Mask: Set bits 7, 6, and 5 to 1. All other bits remain unchanged. Logical Operator: Logical Mask:

shift left/right: Shifting means exactly that, shift all the bits in the first operand either left or right the number of time indicated in the second. The second operand should be an integer value. If it is not, then truncate it (pretend the fractional part does not exist). If a shift left would push a bit off of the 'front', it is lost and causes an overflow. Report the overflow and print the bits left over after the shift. If a shift right would push a bit off of the 'back', it is lost and causes an underflow. Report the underflow and print the bits left over after the shift. e.g. (shift 2 to the left 1 time .. in essence multiply by 2) $ ./compu "000101000010" $ OKAY 1000 (shift 2 to the left 1.5 times .. not an int) $ ./compu "000101000011" $ NINT 1000 (shift 2 to the left 2 times .. in essence multiply by 4, but we can't represent 8) $ ./compu "000101000100" $ AOVR 0000 (shift 1.0 to the left 1 time .. in essence divide by 2) $ ./compu…
this is COmputer machine architecture ! Help me fix the following code as theres an error. what were trying to accoplish; The assignment is to create a MIPS program that corrects bad data using Hamming codes. The program is to request the user to enter a 12-bit Hamming code and determine if it is correct or not. If correct, it is to display a message to that effect. If incorrect, it is to display a message saying it was incorrect and what the correct data is (the 12-bit Hamming code) again in hex. I will be testing only with single bit errors, so the program should be able to correct my tests just fine. You do not need to worry about multiple bit errors. # This program corrects bad data using Hamming codes # It requests the user to enter a 12-bit Hamming code and determines if it is correct or not # If correct, it displays a message to that effect.

*explain plz* You need to explain for each question why you chose True/False as your answer. [6]Assume data toe Int is 32 bits lone and uses a two's- complement representation for signed values The variables are declared and initialized as tollows: int x= too: / Arbitrary value */ int V = barl.* Arbitrary value */ unsigned ux = x: unsigned u = y: The following C expression is true (evaluates to 1) for all values of x and y: x+y == uy+ux. Hint: Think about what happens at bit-level T/F [7] Assume variables ×, f, and d are of type int, float, and double, respectively.
