| | MMX Project Report |
 | | MMX and MMX/SSE versions of the algorithm were implemented directly in assembly. | | | So we can see that adding MMX to the algorithm made the program more memory-bound, although both computation and memory are still very critical to algorithm. | | | First, to further understand how MMX will be useful both now and in the future, we specifically sought out algorithms that were pertinent to developing, up and coming applications of computing technology. |

| | Intel Introduces The Pentium® Processor With MMX Technology |
| | MMX technology maintains complete compatibility with the Intel Architecture and is also fully compatible with widely used operating systems and application software. | | | Broad support for Intel's MMX technology in the software community has led to the development of new educational, reference, games, and communications applications, the first of which are available today and many more of which are expected to be announced throughout the year. | | | Announced last year, Intel's MMX technology is the most significant enhancement to the programmer's view of the Intel architecture in the last 10 years. |

| | BDTI - Intel MMX Pentium |
| | MMX instructions are ``single instruction multiple data'' instructions that operate on the 64-bit-wide MMX registers or on memory in one of the above configurations. | | | The Intel MMX Pentium (designated the ``Pentium with MMX Technology'' by Intel), formally introduced in 1997, is a 32-bit, two-issue superscalar CISC general-purpose processor with support for fixed-point and floating-point arithmetic. | | | The architecture of the MMX Pentium is the same as that of the original Pentium except for number of improvements, the most visible of which are deeper pipelines, larger caches, improved branch prediction, and 57 new instructions intended for DSP, image, and video processing—the MMX instructions. |

| | MMX |
| | MMX had to be kept independent of the current microarchitectures, so that it would scale easily with future advanced microarchitecture techniques and higher processor frequencies in future Intel processors. | | | MMX lets you do more computing per cycle, so the processor has to be able to move data more efficiently. | | | MMX includes new instructions and data types to achieve increased levels of performance on the host CPU by exploiting the parallelism inherent in a great deal of the algorithms in these applications. |

| | MMX - Wikipedia, the free encyclopedia |
| | MMX is rumoured to stand for MultiMedia, Multiple Math or Matrix Math eXtension, but officially it is a meaningless initialism trademarked by Intel. | | | When originally developed in the i860, the use of vectored-integer math made sense (both 2D and 3D setup required it), but as the systems moved to using graphics cards that did this, MMX fell out of favor and vectored-floating point became much more important. | | | The idea that it stands for nothing is an Intel corporate position meant to suggest that it is of trademarked status and cannot be used by AMD or other x86 clone manufacturers in their own marketing material.) |

| | Chapter Eleven The MMX Instruction Set |
| | One drawback to the MMX instruction set is that it is not general purpose. | | | Because the MMX registers overlay the FPU registers, you cannot mix FPU and MMX instructions in the same computation sequence. | | | However, the MMX instructions directly address the needs of modern media, communications, and graphics applications, which often use sophisticated algorithms that perform the same operations on a large number of small data types (bytes, words, and double words). |

| | MMX can only load or store 4 and 8-byte values from memory and works fastest when these reads and writes are aligned. | | | Operations on MMX values are limited to those that Intel decided would be appropriate to sound and image processing. | | | Because this loop processes 4 bytes at a time and MMX works on 8 byte values, "__hint__ ((unroll (2)))" tells VectorC that it should unroll the loop to process 8 bytes at a time. |

| | Either way, you might decide to leave your software as it is. Rest assured that, since new processors with MMX Technology are fully compatible with the instruction set found in previous versions of the Intel Architecture, all of your software will continue to run correctly without requiring any changes. | | | In most cases, optimizing for MMX Technology simply requires implementing those functions using assembly code and the new instructions. | | | While you might not be familiar enough with assembly language programming to follow the flow of the code, you'll notice that the version of the algorithm using MMX instructions is simple enough to place directly in a.cpp module using inline assembly. |
