KEY
ical Memory (PA) addresses to virtual memory
addresses. This allows physical memory, which is
constrained by hardware to specific addresses, to be
reorganized at addresses identified by the user. These
user identified locations are called Virtual Addresses
(VA). When the MMU is enabled, Code and Data must
be built, loaded, and executed using Virtual Addresses
which the MMU translates to Physical Addresses. In
addition, the user may implement a memory protection
scheme by using the features of the MMU. Address
translation and memory protection services provided
by the MMU are controlled by the user. The MMU
is directly controlled through the System Control
Coprocessor, Coprocessor 15 (CP15). The MMU is
indirectly controlled by a Translation Table (TT) and
Page Tables (PT) prepared by the user and estab-
lished using a portion of physical memory dedicated by
the user to storing the TT and PT’s.
