Coherence Manager (CM) is part of the MIPS multi-core cluster IP solution from IMG/MIPS. It maintains coherency for the shared L2 cache, and provides an optional IOCU path for coherent peripheral memory transactions.

There is a family of CM units, including at least CM and CM2.

CM is used with at least the 1004k, 1074k, interAptiv, proAptiv and Warrior generation of cores.
