Please provide the condition codes for each scenario described below. Each problem described is one of the items you must match to the correct set of condition codes. Abbreviations like SA ADDS (Signed Arithmetic, ADDS) are used for simplicity. Assume that all registers are 4 bits long.

**SA ADDS**
- Signed Arithmetic, Instruction ADDS X9, X9, X10
i. X9 = 2, X10 = 7
ii. X9 = -6, X10 = 2
iii. X9 = -6, X10 = -3

**SA SUBS**
- Signed Arithmetic, Instruction SUBS X9, X9, X10
i. X9 = -6, X10 = -4
ii. X9 = -4, X10 = -4
iii. X9 = 5, X10 = -4

**UA ADDS**
- Unsigned Arithmetic, Instruction ADDS X9, X9, X10
i. X9 = 8, X10 = 7
ii. X9 = 8, X10 = 10

**UA SUBS**
- Unsigned Arithmetic, Instruction SUBS X9, X9, X10
i. X9 = 8, X10 = 7
ii. X9 = 9, X10 = 10

Answer :

Final answer:

The condition codes for each scenario are provided based on the given instructions for signed and unsigned arithmetic operations.

Explanation:

For the first scenario, which is a signed arithmetic instruction ADDS x9, x9, x10:

  1. When x9 = 2 and x10 = 7, the sum is positive, so the condition code would be SA ADDS (Signed Arithmetic, ADDS) 001d.
  2. When x9 = -6 and x10 = 2, the sum is negative, so the condition code would be SA ADDS 001k.
  3. When x9 = -6 and x10 = -3, the sum is positive, so the condition code would be SA ADDS 001d.

For the second scenario, which is a signed arithmetic instruction SUBS x9, x9, x10:

  1. When x9 = -6 and x10 = -4, the difference is negative, so the condition code would be SA SUBS (Signed Arithmetic, SUBS) 001c.
  2. When x9 = -4 and x10 = -4, the difference is zero, so the condition code would be SA SUBS 001e.

For the third scenario, which is an unsigned arithmetic instruction ADDS x9, x9, x10:

  1. When x9 = 8 and x10 = 7, the sum is positive, so the condition code would be UA ADDS (Unsigned Arithmetic, ADDS) 001d.
  2. When x9 = 8 and x10 = 10, the sum is positive, so the condition code would be UA ADDS 001d.

For the fourth scenario, which is an unsigned arithmetic instruction SUBS x9, x9, x10:

  1. When x9 = 8 and x10 = 7, the difference is positive, so the condition code would be UA SUBS (Unsigned Arithmetic, SUBS) 001d.
  2. When x9 = 9 and x10 = 10, the difference is negative, so the condition code would be UA SUBS 001c.
