Does it apply to multitasking?
[edit]It seems to me that the term "memory coherence" can also be applied to different tasks (processes or threads) running on a single CPU, as they have to synchronize their interaction in order to remain coherent — although on the software level, rather than the hardware level. Or is the term "memory coherence" only used for the hardware-level concept? -- intgr 12:01, 6 December 2006 (UTC)
As far as I know, coherence is term used only for situation, where there are several copies (replicas) of given datum; i.e. processors with caches, computers with replicas of shared pages etc. Szopen 10:31, 7 December 2006 (UTC)
Should this apply to DMA?
[edit]It seems to me that this should apply to devices as well as processors. A uniprocessor system with devices that use DMA also has to deal with memory coherence. Noah (talk) 22:39, 20 May 2010 (UTC)
