Expert Answer
5.a) MARIE a Machine Architecture that is Really Intuitive and Easy is a simple architecture which consists of memory to store the program and data and CPU. It supports 16bit instructions which are 4 bits for OP Code and 8 bits for address.
i) 0010000000000111

A) This equalent assembly laguage code for this instruction is

Store 007

Explanation:- 0001 0000 0000 0111 is the instruction on these first 4 bits 0001 is for OP Code i.e. operational code and the next 12 bits is the data. First we have to convert this binary form to hexadecimal form, The equalent hexadecimal form for the instruction is 1 0 0 7. And now on this the first bit is OP Code or Instruction. According to the MARIE instruction set the equalent instruction for the hexadecimal bit 1 or binary bit 0001 is Store x.

So Finally the equalent machine language instruction is :Store 007

ii)1001000000001011

A) Like above the hexadecimal form for the above binary instruction is 9 0 0 B.

The MARIE instruction according to instruction set for the bit 9 or 1001 is Jump x.

So Finally the equalent machine language instruction is : Jump 00B

iii) 0011000000001001

A) The hexadecimal form for the above binary instruction is : 3 0 0 9

The MARIE instruction according to instruction set for the bit 3 or 0011 is Add x

So Finally the equalent machine language instruction is : Add 009
