Hello, zverjuga, you wrote: Z> misters, recommend the link where it is possible to download/buy the book on the assembler for a platform x86. The main requirement - freshness of the book. Those books which at me are, old enough, from 15 years and are higher. It would be desirable fresh, modern and actual. Yes, with new books on the assembler it is somehow rather bad on different to the reasons. Especially in Russian it is poorly books. From the oldest and actual it is possible to advise R.Z.Abljazov, - programming on the assembler on a platform x86-64. , 2011 https://www.ozon.ru/context/detail/id/6151449/ the Book any more absolutely new, but from advantages of the book that such things infrequently described in similar books as the correct passage in the 32-bit protected mode and then in a 64-bit mode are considered also. Programming APIC is considered and the multiprocessor (multinuclear) systems - it I generally in other books did not see. From minuses that there are no descriptions FPU, MMX, SSE *, AES and other commands. Absolutely anything is not present about optimization of commands. However the author it, probably also did not set as the purpose, in the book system things though there are also heads of programming in Win32 and Win64 are described in the core. Here http://programmersforum.ru/showthread.php?t=148248 some noted misprints. The author too is present. There are books of Jurova, Zubkov on the assembler, in the last issuings something is about SSE2 and . But if modern interest SIMD extensions it is necessary to search (except specifications) for separate articles and code samples. Something in Russian with it is absolutely feeble.
