Answer #1

--> cmp r1, r2

      cmp will subtract two registers and set the ZERO flag if both are equal.

--> be next

      be will jump to the label given if the ZERO flag was set.

So, the above code snippet will achieve the required effect.


Note: If you have any doubts please comment.

It will be great help If you like.

One can show the MME for this setup is OMME -2 X. As seen in HW2, these estimators are RVs, and each will have its own (sampling) distribution. The sampling distribution gives a good sense of what types of values you'll get from θ when you draw a random sample. Use the...
