Core Complex Overview
5.9
The e500 core complex supports demand-paged virtual memory as well other memory management
schemes that depend on precise control of effective-to-physical address translation and flexible memory
protection as defined by the architecture. The mapping mechanism consists of software-managed TLBs
that support variable-sized pages with per-page properties and permissions. The following properties can
be configured for each TLB:
The core complex employs a two-level memory management unit (MMU) architecture. There are separate
instruction and data level-1 (L1) MMUs backed up by a unified level-2 (L2) MMU.
