wikidata item appearance move to sidebar hide from wikipedia the free encyclopedia instruction set designed by intel pentium with mmx mmx is a single instruction multiple data simd instruction set architecture extension designed by intel introduced on january 8 1997 1 2 with its pentium p5 microarchitecture based line of microprocessors named pentium with mmx technology 3 it developed out of a similar unit introduced on the intel i860 4 and earlier the intel i750 video pixel processor mmx is a processor supplementary capability that is supported on ia 32 processors by intel and other vendors as of 1997 update amd also added mmx instruction set in its k6 processor the new york times described the initial push including super bowl advertisements as focused on a new generation of glitzy multimedia products including videophones and 3 d video games 5 mmx has subsequently been extended by several programs by intel and others 3dnow streaming simd extensions sse and ongoing revisions of advanced vector extensions avx overview edit naming edit mmx is officially a meaningless initialism 6 trademarked by intel 7 unofficially the initials have been variously explained as standing for multimedia extension 1 or matrix math extension 8 advanced micro devices amd during one of its many court battles with intel produced marketing material from intel indicating that mmx stood for matrix math extensions citation needed since an initialism cannot be trademarked citation needed this was an attempt to invalidate intel s trademark in 1995 intel filed suit against amd and cyrix corp for misuse of its trademark mmx amd and intel settled with amd acknowledging mmx as a trademark owned by intel and with intel granting amd rights to use the mmx trademark as a technology name but not a processor name 9 also the mmx term is sometimes confused with the separate multimedia extensions api on windows 3 x and windows 9x technical details edit pentium ii processor with mmx technology mmx defines eight processor registers named mm0 through mm7 and operations that operate on them each register is 64 bits wide and can be used to hold either 64 bit integers or multiple smaller integers in a packed format one instruction can then be applied to two 32 bit integers four 16 bit integers or eight 8 bit integers at once 10 mmx provides only integer operations when originally developed for the intel i860 the use of integer math made sense both 2d and 3d calculations required it but as graphics cards that did much of this became common integer simd in the cpu became somewhat redundant for graphical applications citation needed alternatively the saturation arithmetic operations in mmx could vague significantly speed up some digital signal processing applications citation needed to avoid compatibility problems with the context switch mechanisms in existing operating systems the mmx registers are aliases for the existing x87 floating point unit fpu registers which context switches would already save and restore unlike the x87 registers which behave like a stack the mmx registers are each directly addressable random access any operation involving the floating point stack might also affect the mmx registers and vice versa so this aliasing makes it difficult to work with floating point and simd operations in the same program 11 to maximize performance software often used the processor exclusively in one mode or the other deferring the relatively slow switch between them as long as possible each 64 bit mmx register corresponds to the mantissa part of an 80 bit x87 register the upper 16 bits of the x87 registers thus go unused in mmx and these bits are all set to ones making them not a number nan data types or infinities in the floating point representation this can be used by software to decide whether a given register s content is intended as floating point or simd data hardware support edit amd since amd k6 12 centaur technology since idt winchip c6 cyrix since cyrix 6x86mx 12 intel since intel pentium mmx 13 rise technology rise mp6 transmeta since transmeta crusoe software support edit software support for mmx developed slowly 5 intel s c compiler and related development tools obtained intrinsics for invoking mmx instructions and intel released libraries of common vectorized algorithms using mmx both intel and metrowerks attempted automatic vectorization in their compilers but the operations in the c programming language mapped poorly onto the mmx instruction set and custom algorithms as of 2000 typically still had to be written in assembly language 11 successors edit amd a competing x86 microprocessor vendor enhanced intel s mmx with their own 3dnow instruction set 3dnow is best known for adding single precision 32 bit floating point support to the simd instruction set among other integer and more general enhancements following mmx intel s next major x86 extension was the streaming simd extensions sse introduced with the pentium iii family 14 in 1999 15 roughly a year after amd s 3dnow was introduced sse addressed the core shortcomings of mmx inability to mix integer simd ops with any floating point ops by creating a new 128 bit wide register file xmm0 xmm7 and new simd instructions for it like 3dnow sse focused exclusively on single precision floating point operations 32 bit integer simd operations were still performed using the mmx register and instruction set however the new xmm register file allowed sse simd operations to be freely mixed with either mmx or x87 fpu ops streaming simd extensions 2 sse2 introduced with the pentium 4 further extended the x86 simd instruction set with integer 8 16 32 bit and double precision floating point data support for the xmm register file sse2 also allowed the mmx operation codes opcodes to use xmm register operands extended to even wider ymm and zmm registers by later sse revisions mmx in embedded applications edit intel s and marvell technology group s xscale microprocessor core starting with pxa270 include an simd instruction set architecture extension to the arm architecture core named intel wireless mmx technology iwmmxt which functions are similar to those of the ia 32 mmx extension 16 17 18 it provides arithmetic and logic operations on 64 bit integer numbers in which the software may choose to instead perform two 32 bit four 16 bit or eight 8 bit operations in one instruction the extension contains 16 data registers of 64 bits and eight control registers of 32 bits all registers are accessed through standard arm architecture coprocessor mapping mechanism iwmmxt occupies coprocessors 0 and 1 space and some of its opcodes clash with the opcodes of the earlier floating point extension fpa
