Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Using a hypothetical instruction set where the opcode for ADD is '001', and for LOAD is '010', design a small program using these opcodes to sum two numbers from memory locations 400 and 401 into memory location 402.

💡 Hint: Ensure you specify the full instruction sequence and understand the roles of each opcode.

Challenge 2 Hard

Analyze the use of high-level versus low-level programming languages in terms of speed and ease of maintenance for a project.

💡 Hint: Consider real-world scenarios where either might be more appropriate.
