Device
The processor preserves transaction order relative to other transactions to
Device or Strongly-ordered memory.
Strongly-ordered
The processor preserves transaction order relative to all other transactions.
The different ordering requirements for Device and Strongly-ordered memory mean that the memory
system can buffer a write to Device memory, but must not buffer a write to Strongly-ordered memory.
The additional memory attributes include.
Execute Never (XN)
Means the processor prevents instruction accesses. Any attempt to fetch an
instruction from an XN region causes a memory management fault exception.
2.2.2 Memory system ordering of memory accesses
For most memory accesses caused by explicit memory access instructions, the memory system does not
guarantee that the order in which the accesses complete matches the program order of the instructions,
providing this does not affect the behavior of the instruction sequence. Normally, if correct program
execution depends on two memory accesses completing in program order, software must insert a
memory barrier instruction between the memory access instructions, see Section 2.2.4 (p. 17) .
However, the memory system does guarantee some ordering of accesses to Device and Strongly-
ordered memory. For two memory access instructions A1 and A2, if A1 occurs before A2 in program
order, the ordering of the memory accesses caused by two instructions is:
Norm al access
Device access, non-shareable
Device access, shareable
St rongly-ordered access
Norm al
access
Non-shareable
Shareable
St rongly-
ordered
access
Device access
A1

Where:
-
Means that the memory system does not guarantee the ordering of the accesses.
<
Means that accesses are observed in program order, that is, A1 is always observed before A2.
2.2.3 Behavior of memory accesses
The behavior of accesses to each region in the memory map is:
