Detailed Description

Tree-PLRU-specific implementation of replacement data.

Each replacement data shares its tree with other entries.

Member Data Documentation

◆ index

const uint64_t gem5::replacement_policy::TreePLRU::TreePLRUReplData::index

Theoretical index of this replacement data in the tree.

In practice, the corresponding node does not exist, as the tree stores only the nodes that are not leaves.

Definition at line 140 of file tree_plru_rp.hh.

◆ tree

std::shared_ptr<PLRUTree> gem5::replacement_policy::TreePLRU::TreePLRUReplData::tree

Shared tree pointer.

A tree is shared between numLeaves nodes, so that accesses to a replacement data entry updates the PLRU bits of all other replacement data entries in its set.
