組合語言是很多的用途,例如提高程式的速度,減少記憶體的需要,並控制硬體。若要直接在沒有額外的程式集和連結的步驟 C 和C++ 原始碼程式中嵌入組合語言指令,可以使用內聯彙編。內嵌彙編器是內建編譯器,因此您不需要單獨的彙編器如 Microsoft 的宏彙編器 (MASM)。注意: 內聯彙編代碼的程式不是完全可移植到其他硬體平台。如果您正在設計的可移植性,避免使用內聯彙編。安騰和 x64 處理器不支援內聯程式集。下列主題介紹了如何使用Visual C/C++內聯彙編與 x86 處理器:;====

經過對最新的GotoBlas2核心的分析,dgemm 分解為四個部分:dgemm_beta、dgemm_i*copy、dgemm_kernel、dgemm_o*copy.目標:以Intel Core2 Duo CPU E8500為平台,重新構建(masm文法)最小的dgemm模組。1.dgemm_beta完成:C=BETA*C的運算。先重構dgemm_beta,再給一個簡單的c調用執行個體: ;/**************************************************

BHM File Format readmeThe BHM file format was created by Scali and Samuel R�dal in 2003. At the time they were both involved in the demoscene group Bohemiq, which is where the BHM file format got its name from.The goal was to create a file format
