Challenge Problems
Push your limits with advanced challenges
Design a hypothetical CPU that uses a three-bit Instruction Cycle Code and describe its phases.
💡 Hint: Think about how adding more bits to the ICC might help manage more phases.
Consider a scenario where an interrupt occurs while the CPU is in the decode phase; how would your system manage the state?
💡 Hint: What steps need to happen to ensure that data can be retrieved?
