Multiple threads can interfere with each other when sharing hardware resources such as caches or translation lookaside buffers (TLBs). As a result, execution times of a single thread are not improved and can be degraded, even when only one thread is executing, due to lower frequencies or additional pipeline stages that are necessary to accommodate thread-switching hardware.
Multics hardware was the first significant implementation of ring security, but many other hardware platforms have been designed along similar lines, including the Intel 80286 protected mode, and the IA-64 as well, though it is referred to by a different name in these cases. Mode protection may extend to resources beyond the CPU hardware itself.
The execution time of the whole task before the improvement of the resources of the system is denoted as . It includes the execution time of the part that would not benefit from the improvement of the resources and the execution time of the one that would benefit from it.
Nehalem / n ə ˈ h eɪ l əm / [1] is the codename for Intel's 45 nm microarchitecture released in November 2008. [2] It was used in the first generation of the Intel Core i5 and i7 processors, and succeeds the older Core microarchitecture used on Core 2 processors. [3]
Also isometric graphics. Graphic rendering technique of three-dimensional objects set in a two-dimensional plane of movement. Often includes games where some objects are still rendered as sprites. 360 no-scope A 360 no-scope usually refers to a trick shot in a first or third-person shooter video game in which one player kills another with a sniper rifle by first spinning a full circle and then ...
A style guide to British English usage, H.W. Fowler's A Dictionary of Modern English Usage, states in the first edition (1926) that applying the word nigger to "others than full or partial negroes" is "felt as an insult by the person described, & betrays in the speaker, if not deliberate insolence, at least a very arrogant inhumanity"; but the ...
Executing heavy AVX instructions at high CPU clock frequencies may affect CPU stability due to excessive voltage droop during load transients. Some Intel processors have provisions to reduce the Turbo Boost frequency limit when such instructions are being executed.
As one of the first widely available processors with a 32-bit instruction set, large unsegmented address space, and relatively high speed for the era, the 68k was a popular design through the 1980s. It was widely used in a new generation of personal computers with graphical user interfaces , including the Macintosh 128K , Amiga , Atari ST , and ...
