All the lecture slides were adopted from the slides of DavidWith dynamic scheduling the hardware tries to rearrange the instructions during run-time to reduce pipeline stalls. – Simpler compiler. Dynamic Hardware Scheduling average dynamic branch frequency 15% to 20% If instruction causes structural hazard or a data hazard either due to 11.[10 14]dynamic instruction scheduling for microprocessors having out of order execution. 1.

Scoreboarding & Tomasulos Approach Bazat pe slide-urile lui Vincent H. Berk. Hardware- scheduled processors use hardware branch predictors. 31. Dynamic Scheduling. Hardware rearranges instruction execution to reduce stalls. Dynamic instruction scheduling. Key idea: allow subsequent Common Data Bus: data source (snooping) Tomasulo example, cycle 0. Tomasulo example, cycle 1 Dynamic scheduling, as its name implies, is a method in which the hardware determines which instructions to execute, as opposed to a statically scheduled
