The 68030 can be used with the 68020 bus, in which case its performance is similar to 68020 that it was derived from. However, the 68030 provides an additional synchronous bus interface which, if used, accelerates memory accesses up to 33% compared to an equally clocked 68020. The finer manufacturing

Neither the PMMU nor the 68030 MMU constitutes a proper superset of the other. The PMMU has instructions and registers not found in the 68030 MMU, while the latter has registers not on the PMMU. However, in a typical Unix implementation little work would needed to port PMMU specific code to the
