A 32-bit IA-32 processor supports locking atomic operations on locations in system memory. These operations are generally used for shared data structures (such as semaphores, segment descriptors, system segments, and page tables ). For these shared data structures, there may be two or more processors trying to modify their same domain at the same time (Translator's note: it is equivalent to a data member of the struct variable in C) or sign. The processor uses three interdependent mechanisms to

On July 15, May 28, Beijing time, according to foreign media reports, the German Financial Times Deutschland quoted a message on Tuesday that the European Union will impose anti-monopoly sanctions on Intel due to violation of the anti-monopoly law. According to sources, the European Union has determined that intel has abused its dominant market advantage in Europe. The European Union plans to officially an

Performance | intel Last weekend Intel blamed "AMD for attacking Intel as a fake double," and came up with a third party review to show that AMD duo processors perform very low performance when multitasking.June 2005, the foreign hardware site Tomshardware to the Intel P840ee and AMD A64 X2 4800+ of the comparative e

Journalist/Dong Xixiao As the first chief engineer to emerge from the Intel China Institute, Wugansha's story may enlighten us. He believes that no matter what you do, as long as you take it seriously, even if you go a detour, you can also achieve another success. Chief Engineer's responsibility, rights and benefits 　　"Programmer": first of all, congratulations on your becoming Intel's chief engineer, please describe the job responsibilities of the

1. clock speed The clock speed is also called the clock frequency. The unit is MHz, which indicates the computing speed of the CPU. CPU clock speed = frequency X frequency doubling coefficient. Many people think that the clock speed determines the CPU running speed. This is not only one-sided, but also a misunderstanding of the server. So far, there is no definit

last year's Skylake six Daicouri processor release, Intel launched a 100-series chipset for the new LGA1151 interface, which is the H/B/Z 100 system motherboard. Kaby Lake Processor Although this year's Kaby Lake desktop processor does not change the interface, that is, the 100-series motherboard can still be upgraded seamlessly, but in order to fit its Optane nonvolatile storage technology (based on its solid-state hard disk, memory is

This chapter is selected from the Intel official documentation and translated by myself. Note that the following English word cache is used. If C is in uppercase, that is, cache, it indicates the term "cache". If C is in lowercase, that is, cache, indicates the verb -- indicates saving data to a high-speed buffer storage. Intel 64 and the IA-32 architecture provide the ability to manage and enhanc
