Q. Show the conflict in register?
All micro-operations written on a line are to be executed at same time provided the statements or a group of statements to be implemented together are free of conflict. A conflict takes place if two different contents are being transferred to a single register at same time. For illustration the statement: new line X: R1← R2, R1←R3 signifies a conflict since both R2 and R3 are trying to transfer their contents to R1 at the same instance.
