Learning objective:
- Recognise the principle of Little Man Computer - the CPU simulator
Success Criteria:
- Identify the concept of Assembly languages
- Explain the purpose of LMC
- Describe the functions of LMC
What is Assembly language?
- Translates high-level code into machine code and vice versa
- Low-level language
- Uses 'mnemonics' to represent machine code
- Each instruction corresponds to just one machine operation
LMC instruction set - code that can be executed by the central processing unit
