Introduction

This repository provides sample C++ code illustrating the utilization of MMX, SSE, SSE2, and AVX instructions.

Code Overview

The repository consists of two source files:

1. sample_code.cpp:
   • Demonstrates the usage of MMX, SSE, and SSE2 instructions.
   • Performs operations such as comparing vectors, adding elements, computing square roots, and finding minimum elements.
   • Utilizes both inline assembly and intrinsic functions.
2. mmx_sse_avx.cpp:
   • Expands the usage to include AVX instructions along with MMX, SSE, and SSE2.
   • Implements functions using data formats __m64, __m128, and __m256.
   • Performs vector addition, square root calculation, and comparison of elements to find the minimum.

Instructions

clang++ ./sample_code.cpp -std=c++20 -Ofast -march=native -o sample_code.exe
clang++ ./mmx_sse_avx.cpp -std=c++20 -Ofast -march=native -o mmx_sse_avx.exe
