Challenge Problems

Push your limits with challenges.

Question 1

Design an instruction format for a hypothetical CPU that uses 4 bits for opcode and 12 bits for an immediate value. Explain your design decisions.

💡 Hint: Consider the types of operations your CPU needs and the range of immediate values.

Question 2

Explain how the encoding of addressing modes can impact the performance of a CPU. Provide a comparison between immediate and indirect addressing.

💡 Hint: Think about the speed of accessing data and how it flows through the CPU.
