Consider a computer that has a number of registers such that the three registers r0 = 1500, r1 = 4500, and r2 = 1000. show the effective address of memory and the registers’ contents in each of the following instructions (assume that all numbers are decimal).
(a) add (r0)+, r2
(b) subtract - (r1), r2
(c) move 500(r0), r2
(d) load #5000, r2
(e) store r0, 100(r2)
