Abstract
A data processing apparatus has control circuitry for detecting whether a first micro-operation to be processed by a first processing lane would give the same result as a second micro-operation processed by a second processing lane. If they would give the same result, then the first micro-operation is prevented from being processed by the first processing lane and the result of the second micro-operation is output as the result of the first micro-operation. This avoids duplication of processing, to save energy for example.
