Challenge Problems
Push your limits with advanced challenges
Suppose you have a CPU with a 12-bit address bus and a 16-bit data bus. Calculate the maximum memory that can be addressed and how many different instructions can be defined given a 4-bit opcode.
💡 Hint: Consider how binary powers work for memory addressing.
Describe how the CPU could process a sequence of three instructions: LOAD from memory, ADD a value, and STORE the result back. Specify the role of the relevant registers.
💡 Hint: Focus on the flow of data and where it is held during each step.
