Leverage target hardware instruction set extensions

SIMD instruction set for target hardware

Since R2021b

Description

App Configuration Pane: Speed

Configuration Objects: | coder.CodeConfig | coder.EmbeddedCodeConfig

The Leverage target hardware instruction set extensions parameter specifies the instruction sets to use to generate single instruction, multiple data (SIMD) code for target hardware. The list of options in the Settings section shows the dependency of the instruction sets, where each instruction set depends on the instruction sets that precede it. The code generator loads the selected instruction set and the instruction sets that it depends on. For example, if you select AVX, the code generator loads AVX, SSE4.1, SSE2, and SSE.

If you select Auto, the code generator selects an instruction set according to your hardware board:

  • MATLAB® Host Computer, Intel®, or AMD® — SSE2

  • ARM® — None

See Generate SIMD Code from MATLAB Functions for Intel Platforms.

When using GPU Coder™, the code generator always disables this parameter.

Settings

Auto

The code generator selects an instruction set according to your hardware board. This value is the default value.

None

The code generator does not produce SIMD code.

SSE

The code generator produces SIMD code that uses the SSE instruction set.

SSE2

The code generator produces SIMD code that uses the SSE2 instruction set.

SSE4.1

The code generator produces SIMD code that uses the SSE4.1 instruction set.

AVX

The code generator produces SIMD code that uses the AVX instruction set.

AVX2

The code generator produces SIMD code that uses the AVX2 instruction set.

FMA

The code generator produces SIMD code that uses the FMA instruction set.

AVX512F

The code generator produces SIMD code that uses the AVX512F instruction set.

Neon v7

The code generator produces SIMD code that uses the Neon v7 instruction set.

Dependencies

The list of available instruction sets depends on the value of the Hardware board parameter.
