Implementing strcmp, strlen, and strstr using SSE 4.2 instructions by Peter Kankowski agner (31) fog instruction optimization optimizing x86 tables cpu assembly today subroutines In this video we'll explore some more advanced algorithms using Agner Fog's Vector Class Library. These are graphical examples, fractals, emulating HDR (High Agner Fog's 64bit memcpy. GitHub Gist: instantly share code, notes, and snippets. Hi, I was wondering what is the latency and throughput of the vbroadcastsd instruction? (This is for Sandy Bridge) I did not find that information in the Optimization Reference Manual.

テクノロジーカテゴリーの変更を依頼記事元: www.agner.org Agner Fog is known as a "CPU analyst" to tech websites covering x86 CPUs. [2] [4] He maintains a five-volume manual for optimizing code for x86 CPUs, with details on the instruction timing and other features of individual microarchitectures . Intel flavors often do both with a single idiv instruction.

Agner Fog's "microarchitecture.pdf" (https://www.ag Agner Fog: Email: agner@agner.org: details about the microarchitecture and instruction timings of Intel and AMD processors, Instruction Tables; Part 5: An open forward-compatible instruction set architecture. Contents: A large page table requires fixed-size memory pages in order to make table By Agner Fog Agner Fog Optimization Guides. Optimizing software in C++ : An optimization guide for Windows, Linux and Mac platforms; Optimizing subroutines in assembly language : An optimization guide for x86 platforms; The microarchitecture of Intel, AMD and VIA CPUs : An optimization guide for assembly programmers and compiler makers In this video we'll look at installing Agner Fog's VCL (Vector Class Library). We look at installing the library, as well as an overview of the vector types, Hennessy and Patterson don't cite Fog and that's just crazy. H+P then get basic facts about x86 architecture and microarchitecture wrong "The length of 80x86 instructions varies between 1 and 17 bytes." CA 5th, p A-23.

The definition of the throughput: is the time in [cycle] to perform a new identical mnemonic. Hmm, no, those latency timings appear to include an L1 access for some strange reason.
