Quiz on Delay and Bypass Techniques in Out-of-Order Processors

The purpose of flexible instruction scheduling in out-of-order processors is to improve performance.

Flexible instruction scheduling is typically achieved by using CAM-based Instruction Queues (IQs).

The drawback of using CAM-based Instruction Queues (IQs) is the significant scheduling energy cost.

<p>This work aims to reduce instruction scheduling energy by reducing the depth and width of the IQ.</p> Signup and view all the answers
