Given a macro instruction that involves several arithmetic and logical operations, break down the instruction into its respective micro instructions and identify how many clock cycles would be required to execute each part.
💡 Hint: Consider how many steps are involved in each part of your macro instruction.
Design a simple instruction set and for a specific instruction, identify potential micro instructions. Discuss how clock grouping could optimize the instruction's execution.
💡 Hint: Look at the operations involved and see which ones can run in parallel.
