Challenge Problems
Push your limits with advanced challenges
Design a multiplexer configuration for a scenario where three conditions must be checked to determine the flow of execution for micro-instructions. Detail how you would implement control signals for each condition.
💡 Hint: Think about the logic needed for each input setting.
Given a micro-program counter that needs to handle both incrementing and jumping based on a complex set of conditions, propose a set of signals and conditions to effectively manage the execution path.
💡 Hint: Consider the efficiency of how signals determine actions for every scenario.
