Q72

Consider the following program segment. Here $\text{R1, R2}$ and $\text{R3}$ are the general purpose registers.

$$\small \begin{array}{|c|l|l||c|} \hline & \text {Instruction} & \text{Operation }& \text{Instruction Size} \\ & & & \text{(no. of words)} \\\hline & \text{MOV R1,(3000)} & \text{R1} \leftarrow \text{M[3000]} & 2 \\\hline \text{LOOP:}& \text{MOV R2,(R3)} & \text{R2} \leftarrow \text{M[R3]} & 1 \\\hline & \text{ADD R2,R1} & \text{R2} \leftarrow \text{R1 + R2} & 1 \\\hline & \text{MOV (R3),R2} & \text{M[R3]} \leftarrow \text{R2} & 1 \\\hline& \text{INC R3} & \text{R3} \leftarrow \text{R3 + 1} & 1 \\\hline & \text{DEC R1} & \text{R1} \leftarrow \text{R1 – 1} & 1 \\\hline& \text{BNZ LOOP} & \text{Branch on not zero} & 2 \\\hline & \text{HALT} & \text{Stop} & 1 \\\hline\end{array}$$

Assume that the content of memory location $3000$ is $10$ and the content of the register $\text{R3}$ is $2000$. The content of each of the memory locations from $2000$ to $2010$ is $100$. The program is loaded from the memory location $1000$. All the numbers are in decimal. Assume that the memory is word addressable. After the execution of this program, the content of memory location $2010$ is:
