Current superscalar architectures inherently depend on an instruction issue queue to achieve multiple instruction issue and out-oforder execution. However, the issue queue is implemented as a centralized structure and mainly causes globally broadcasting operations to wake up and select the instructions. Therefore, a large issue queue ultimately results in a… CONTINUE READING
