Memory disambiguation
open-in-new
<p>Memory disambiguation is a set of techniques employed by high-performance <a href="/facts/Out-of-order_execution/bM0dQM8m">out-of-order execution</a> <a href="/facts/Microprocessor/Fx9CaQht">microprocessors</a> that execute <a href="/facts/Primary_storage/wPHKFpdx">memory</a> access <a href="/facts/Instruction_(computer_science)/8p8vwUeE">instructions</a> (loads and stores) out of program order. The mechanisms for performing memory disambiguation, implemented using <a href="/facts/Digital_circuit/vWgfC29C">digital logic</a> inside the microprocessor core, detect true dependencies between memory operations at execution time and allow the processor to recover when a dependence has been violated. They also eliminate spurious memory dependencies and allow for greater <a href="/facts/Instruction-level_parallelism/2W8qvN8K">instruction-level parallelism</a> by allowing safe out-of-order execution of loads and stores. </p>
