i)
^= is a Bitwise exclusive or operator. A^=0x8001 is same as A = A ^
0x8001
ii)
value of i = 0x8808 is 32776
>> is bitwise Right shift operator.
so,
i= i >> 5 means shifting value of 32776 by 5 bits.

Question 20 5 pts Suppose a computer has 32-bit instructions. The instruction set consists of 64 different operations. All instructions have an opcode and two address fields (allowing for two addresses). The first of these addresses must be a register direct address, and the second must be a memory address. Expanding opcodes are not used. The machine has 16 registers. How many bits can be used for the memory address? Question 21 5 pts Suppose we have...

Exercise 1 (9 pts) We have seen that ARM has 16*32 bits registers (plus floating point registers) There is also a status register: CPSR. It contains, among other things, the following important status bits N Negative, set when the result of an arithmetic operation is negative (according to the two's complement encoding of the natural numbers . Z- Zero, set when the result of an operation is zero . C Carry, set when an operation results in a carry bit...
