Transcribed Image Text:**Question 6: Conversion from Machine Language to Assembly Language for MARIE**
**Objective:**
Translate the given MARIE machine language instructions into their assembly language equivalents.
**Instructions:**
a) **Machine Language:** 0000010111000000
- **Assembly Language:** ADD X
b) **Machine Language:** 0001101110010010
- **Assembly Language:** SUB Y
c) **Machine Language:** 1100100101101011
- **Assembly Language:** JUMP Z
**Explanation:**
- MARIE (Machine Architecture that is Really Intuitive and Easy) is a simple educational model of a computer that helps students and learners understand basic computer architecture and assembly language.
- Each machine language instruction consists of a 16-bit binary code, with the first four bits typically representing the opcode and the remaining bits representing the address or data.
- The conversion requires familiarity with MARIE’s instruction set, where particular opcodes correspond to specific operations (e.g., ADD, SUB, JUMP), followed by an address or a data label reference.
This exercise helps in understanding how high-level assembly translations correspond directly to binary operations executed by the machine. Learners are encouraged to practice translating more instructions to enhance their understanding of computer instruction sets.
