Question

The contents of the URM register can be altered by certain instructions that it can recognize. Describe one application of each of instruction.

Answer 1

A URM has an infinite number of register labeled R,r2,.....

Every register can hold a natural number at any instance.

[r1,r2,r3]³1[r4]₄^{4 and so on...}

^{We can altered certain instructions by replace,transfer method:}

^{lets discuss what type of instructions are there:}

zero Replace rn by 0 (e.g.0->Rn or rn->0)

successor Add 1 to rn(rn+1->Rn)

Transfer like copy copy rm to Rn( rm->Rn)

Jump if rm=rn then go to q^th instruction otherwise go to the next instruction.
