demand paged การใช้

• The last 386 versions supported virtual memory, but not demand paging.
• This scheme is generally known as demand paging.
• He now describes that as an " edit war " and demands page protection.
• The incomplete DPMI implementation and the lack of support for virtual memory ( demand paging, C ).
• In RE : song being played nationally, the video has received MTV airplay and is still listed on their On Demand page.
• DG / UX 5.4, released around 1991, replaced the legacy Unix file buffer cache with unified, demand paged virtual memory management.
• These schemes were superseded by virtual memory, demand paging operating systems that made use of 32bit addressing capabilities that were introduced in the Intel 80386 processor.
• GCOS 8 was an extensive rewrite of GCOS 3, with changes made to support true virtual memory management and demand paging ( these changes also required new hardware ).
• Another example of laziness in modern computer systems is copy-on-write page allocation or demand paging, where memory is allocated only when a value stored in that memory is changed.
• Apollo's networking was particularly elegant, among the first to allow demand paging over the network, and allowing a degree of network transparency and low sysadmin-to-machine ratio.
• MonetDB internal data representation also relies on the memory addressing ranges of contemporary CPUs using demand paging of memory mapped files, and thus departing from traditional DBMS designs involving complex management of large data stores in limited memory.
• Memory-mapping may not only bypass the page file completely, but the system only needs to load the smaller page-sized sections as data is being edited, similarly to demand paging scheme used for programs.
• Bolt, Beranek, and Newman developed TENEX for a modified PDP-10 that supported demand paging; this was another popular system in the research and ARPANET communities, and was later developed by DEC into TOPS-20.
• This is that Wikipedian mentioned in the lede of this oh-no-not-yet-another-board-essay as a way to reject good faith and demand page-cites " when they are not needed ".
• In Java, the New IO ( java . nio . * ) package, ( documentation ) and its Channels methodology, allow you to do the same-with the VM overseeing the demand paging and swapping of buffers into and out of memory.
• A 32-bit system with a CISC architecture based on DEC's earlier PDP-11, VAX ( " " virtual address extension " " ) was designed to extend or replace DEC's various demand paged virtual memory ) and its orthogonal instruction set.
• Yet I'm the one in hot water because of " his " onslaught of half-truths and rule-happy things like this discussion-" it's OK if I demand page-cites for " anything ", right ? ".
• There was a project, codenamed " Alice ", to develop the 3B5 into an asymmetric multiprocessor with 3 CPUs, but this was canceled in favor of the demand paging 3B15 project, and a few of the " Alice " participants left the company and went to Sequent Computer Systems.
• These S / 360-67 features plus reference and change bits as part of the storage key enabled operating systems to implement demand paging : referencing a page that was not in memory caused a page fault, which in turn could be intercepted and processed by an operating system interrupt handler.
• You could do demand paging perfectly well out of a file on a read-only disk, and as far as I know this would be exactly what would happen if you were to exec an a . out file ( i . e . a Unix executable ) in a directory on a mounted CD-ROM filesystem.
