Simd in a sentence

Strided load/store instructions Special instructions to load homogeneous data from multiple elements in AoS format into a single SIMD register SIMD register SoA a de-interleaved memory layout amenable to SIMD processing.

SIMD instructions are widely used to process 3D graphics, although modern graphics cards with embedded SIMD have largely taken over this task from the CPU.

Adoption of SIMD systems in personal computer software was at first slow, due to a number of problems.

A homogeneous processor system typically requires extra registers for "special instructions" such as SIMD (MMX, SSE, etc.), while a heterogeneous system can implement different types of hardware for different instructions/uses.

Apple Computer had somewhat more success, even though they entered the SIMD market later than the rest.

A recent advancement by Ziilabs was the production of an SIMD type processor which can be used on mobile devices, such as media players and mobile phones.

However, since processor support for any SSE revision also implies support for MMX, the removal does not limit the data types usable by x86 SIMD.

However, the new XMM register-file allowed SSE SIMD-operations to be freely mixed with either MMX or x87 FPU ops.

Instances of these types are immutable and in optimized code are mapped directly to SIMD registers.

Instead of a series of instructions saying "retrieve this pixel, now retrieve the next pixel", a SIMD processor will have a single instruction that effectively says "retrieve n pixels" (where n is a number that varies from design to design).

Intel's AVX SIMD instructions now process 256 bits of data at once.

Intel's first IA-32 SIMD effort was the MMX instruction set.

Intel's Sandy Bridge processors added the AVX (Advanced Vector Extensions) instructions. widening the SIMD registers to 256 bits.

It differs from traditional ISAs by being SIMD from the ground up with no separate scalar registers.

It is roughly 10% faster than Thunderbird at the same clock speed, thanks in part to the new SIMD functionality and to several additional improvements.

It was the first instruction set to exploit floating-point SIMD with existing resources.

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.

Microsoft 's Direct3D 9.0 now chooses at runtime processor-specific implementations of its own math operations, including the use of SIMD-capable instructions.

Modern graphics processing units (GPUs) are often wide SIMD implementations, capable of branches, loads, and stores on 128 or 256 bits at a time.

Progressively, these early designs were refined and remade into some of the common, modern SIMD specifications, which are usually associated with one ISA.
