Memory Management Unit (MMU)

MSC8144E Reference Manual, Rev. 3

Freescale Semiconductor

11-3

Hardware data and program access protection is defined for each data/program memory
region for two privilege levels: user and supervisor. The MMU provides abort signals for
the Xa/Xb/P buses for errant accesses. The MMU provides memory region support, as
follows:

— For the program memory region: Provides supervisor-level read allowed/not allowed

access; for the User level, provides read allowed/not allowed access

— For the data memory region: Provides read/write allowed/not allowed for both the

Supervisor and User levels

Address translation is defined for each data/program memory region, enables allocating
virtual memory region to a valid physical memory space.

Priority mechanism between descriptors, allowing memory regions overlapping.

Stores the program task ID and data task ID for multi-task mechanism. Up to 255 different
Program IDs and 255 different data IDs are available.

General Purpose registers among its control and status registers.

Access error detection including non-mapped memory access and misaligned memory
access.

Captures error status bits and enables a fast error diagnostic.

Precise interrupts allowing handling MMU MATT misses supporting a virtually paged
operating system.

Core branch target buffer (BTB) that enables manual and automatic BTB maintenance.

Platform error detection code (EDC) recovery scheme.

Enable/disable EDC exception mechanism.

Peripherals error handling.
