MMX TECHNOLOGY

This guide explores MMX (Multi-Media eXtension) technology, designed to enhance multimedia and communication applications through acceleration. It leverages the parallelism of multimedia algorithms and introduces innovative features such as the Single Instruction Multiple Data technique, 57 new instructions, and new data types. The study focuses on the Pentium Processor's pipeline structure, implementing matrix operations (multiplication and transformation), and optimizing code for efficiency. It aims to identify opportunities for effectively using MMX instructions, improving performance through data caching, loop unrolling, and code optimization.
