Suppose we have a hypothetical processor, of which each register has only five bits. r0 = 0b11101 and r1 = 0b10110. What are the N,Z,C, and V flags of the following instructions? Assume initially N = 0, Z = 0, C = 1, V = 0, and these instructions are executed independently (1) ADDS r3, r0, r1 (2) SUBS r3, r0, r1 (3) EOR r3, r0, r1 (4) ANDS r3, r1, r1, LSL #3

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...

Compute the correct CPU computations and actions.
Write the final updated values for each memory, register and
flags after the given instruction executes in the space provided.
There are multiple parts of this problem.
Endianness: Check for endianness in case of loads and stores, in
each part of the question. If the question does not specify the
endianness, you can assume little-endian.

Write the final updated values for each memory and register
after the given instruction executes in the space provided.There
are multiple parts of this problem. Note Only write the change
values if the values didn't change. Leave the updated cell
blank.
