The x86 instruction set refers to the set of instructions that x86-compatible microprocessors support. The instructions are usually part of an executable program, often stored as a computer file and executed on the processor. The x86 instruction set has been extended several times, introducing wider registers and datatypes as well as new ...
The later Pentium MMX also added the MMX instruction set, a basic integer single instruction, multiple data instruction set extension marketed for use in multimedia applications. MMX could not be used simultaneously with the x87 FPU instructions because the registers were reused (to allow fast context switches). More important enhancements were ...
Pentium with MMX. MMX is a single instruction, multiple data instruction set architecture 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]
The x86 instruction set has several times been extended with SIMD (Single instruction, multiple data) instruction set extensions.These extensions, starting from the MMX instruction set extension introduced with Pentium MMX in 1997, typically define sets of wide registers and instructions that subdivide these registers into fixed-size lanes and perform a computation for each lane in parallel.
Due to its prominence, the term "Pentium-compatible" is often used to describe any x86 processor that supports the IA-32 instruction set and architecture. Even though they do not use the Pentium name, Intel also manufactures other processors based on the Pentium series for other markets.
The Pentium III [2] (marketed as Intel Pentium III Processor, ... (SSE) instruction set (to accelerate floating point and parallel calculations), ...
MMX is a SIMD instruction set designed by Intel and introduced in 1997 for the Pentium MMX microprocessor. [40] The MMX instruction set was developed from a similar concept first used on the Intel i860. It is supported on most subsequent IA-32 processors by Intel and other vendors.
In computing, Streaming SIMD Extensions (SSE) is a single instruction, multiple data instruction set extension to the x86 architecture, designed by Intel and introduced in 1999 in its Pentium III series of central processing units (CPUs) shortly after the appearance of Advanced Micro Devices (AMD's) 3DNow!.
