Detailed Description

"Universal intrinsics" is a types and functions set intended to simplify vectorization of code on different platforms. Currently a few different SIMD extensions on different architectures are supported. 128 bit registers of various types support is implemented for a wide range of architectures including x86(SSE/SSE2/SSE4.2), ARM(NEON), PowerPC(VSX), MIPS(MSA). 256 bit long registers are supported on x86(AVX2) and 512 bit long registers are supported on x86(AVX512). In case when there is no SIMD extension available during compilation, fallback C++ implementation of intrinsics will be chosen and code will work as expected although it could be slower.

Types

There are several types representing packed values vector registers, each type is implemented as a structure based on a one SIMD register.

Exact bit length(and value quantity) of listed types is compile time deduced and depends on architecture SIMD capabilities chosen as available during compilation of the library. All the types contains nlanes enumeration to check for exact value quantity of the type.

In case the exact bit length of the type is important it is possible to use specific fixed length register types.

There are several types representing 128-bit registers.

There are several types representing 256-bit registers.

Note
256 bit registers at the moment implemented for AVX2 SIMD extension only, if you want to use this type directly, don't forget to check the CV_SIMD256 preprocessor definition:
#if CV_SIMD256
//...
#endif

There are several types representing 512-bit registers.

These operations allow to set contents of the register explicitly or by loading it from some memory block and to save contents of the register to memory block.

There are variable size register load operations that provide result of maximum available size depending on chosen platform capabilities.

Also there are fixed size register load/store operations.

For 128 bit registers

For 256 bit registers(check CV_SIMD256 preprocessor definition)

For 512 bit registers(check CV_SIMD512 preprocessor definition)

Store to memory operations are similar across different platform capabilities: v_store, v_store_aligned, v_store_high, v_store_low

Value reordering

These operations allow to reorder or recombine elements in one or multiple vectors.

Arithmetic, bitwise and comparison operations

Element-wise binary and unary operations.

Reduce and mask

Most of these operations return only one value.

Other math

Conversions

Different type conversions and casts:

Matrix operations

In these operations vectors represent matrix rows/columns: v_dotprod, v_dotprod_fast, v_dotprod_expand, v_dotprod_expand_fast, v_matmul, v_transpose4x4

Usability

Most operations are implemented only for some subset of the available types, following matrices shows the applicability of different operations to the types.
