Ensuring back-to-back execution of dependent instructions in a conventional out-of-order processor requires scheduling logic that wakes up and selects instructions at the same rat...
Conventional speculative architectures use branch prediction to evaluate the most likely execution path during program execution. However, certain branches are difficult to predic...

Modern microprocessors adopt speculative scheduling techniques where instructions are scheduled several clock cycles before they actually execute. Due to this scheduling delay, sc...
To achieve high instruction throughput, instruction schedulers must be capable of producing high-quality schedules that maximize functional unit utilization while at the same time...
Operand bypass logic might be one of the critical structures for future microprocessors to achieve high clock speed. The delay of the logic imposes the execution time budget to be ...
