Abstract
This disclosure provides techniques and apparatuses to enable early, run-ahead handling of IC and ITLB misses by decoupling the ITLB and IC tag lookups from the IC data (instruction bytes) accesses, and making ITLB and IC tag lookups run ahead of the IC data accesses. This allows overlapping the ITLB and IC miss stall cycles with older instruction byte reads or older IC misses, resulting in fewer stalls than previous implementations and improved performance
