Class Hierarchy

conf-object → log-object → trans-splitter-ooo

Interfaces Implemented

log_object, timing_model

Description

A trans-splitter-ooo object can split a transaction that crosses a cache line in two non-crossing transactions.

A trans-splitter-ooo can be inserted between the cpu and the caches if the cpu can issue cache-line crossing transactions (x86 being a good example). It can also be used between two caches to split transactions.

A trans-splitter-ooo object supports multiple outstanding transactions. Note that it does not support splitting a transaction more than once, so transactions that crosses two cache lines or more will be split incorrectly.
