Memory ordering is the order of accesses to computer memory by a CPU. Memory ordering depends on both the order of the instructions generated by the compiler...

causes a central processing unit (CPU) or compiler to enforce an ordering constraint on memory operations issued before and after the barrier instruction....

Deviation in ordering Ordering deviation is the discrepancy between the local order of writes in a replica and their relative ordering in the eventual...

their associated memory. File formats can use either ordering; some formats use a mixture of both or contain an indicator of which ordering is used throughout...

locked XCHG. This is due to subtle memory ordering rules which support this, even though MOV is not a full memory barrier. However, some processors (some...

such a high level of translation efficiency is the support of x86-64 memory ordering in the M1 SoC. The SOC also has dedicated instructions for computing...

Most lock-less algorithms are built on top of memory barriers for the purpose of enforcing memory ordering and prevent undesired side effects due to compiler...

Random-access memory (RAM; /ræm/) is a form of electronic computer memory that can be read and changed in any order, typically used to store working data...

chronological ordering (e.g., the memory of a story or a movie scene). The episodic buffer is also assumed to have links to long-term memory and semantic...

sufficient memory ordering guarantees (i.e. memory barriers). Most C and C++ compilers, linkers, and runtimes simply do not provide the necessary memory ordering...

M3: Burst type. 0 - requests sequential burst ordering, while 1 requests interleaved burst ordering. M2, M1, M0: Burst length. Values of 000, 001, 010...

execute their instructions in an out-of-order fashion; even memory accesses can be reordered (see memory ordering). This algorithm won't work on SMP machines...

done with pure shared memory approaches. Most modern CPUs reorder memory accesses to improve execution efficiency (see memory ordering for types of reordering...

Semiconductor memory is a digital electronic semiconductor device used for digital data storage, such as computer memory. It typically refers to devices...

includes minimal support in the form of a fence instruction to enforce memory ordering.: 26–27  Although this is sufficient (fence r, rw provides acquire...

contrast, volatile memory needs constant power in order to retain data. Non-volatile memory typically refers to storage in memory chips, which store data...
