Challenge Problems
Push your limits with advanced challenges
Imagine you have a simple CPU that only supports single-address instructions. You need to calculate the sum of two values stored at different memory addresses. How would you design the required instructions and what would the implications be for the program counter?
💡 Hint: Think about how you could represent adding two numbers without direct access to both at once.
A multi-address instruction allows you to add two numbers and store the result in a third memory location. Provide an example of an assembly instruction that accomplishes this, and explain how the PC updates after each instruction.
💡 Hint: Focus on the efficiency improvements allowed by multi-addressing.
