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.

• cv::v_uint8 and cv::v_int8: 8-bit integer values (unsigned/signed) - char
• cv::v_uint16 and cv::v_int16: 16-bit integer values (unsigned/signed) - short
• cv::v_uint32 and cv::v_int32: 32-bit integer values (unsigned/signed) - int
• cv::v_uint64 and cv::v_int64: 64-bit integer values (unsigned/signed) - int64
• cv::v_float32: 32-bit floating point values (signed) - float
• cv::v_float64: 64-bit floating point values (signed) - double

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.

• cv::v_uint8x16 and cv::v_int8x16: sixteen 8-bit integer values (unsigned/signed) - char
• cv::v_uint16x8 and cv::v_int16x8: eight 16-bit integer values (unsigned/signed) - short
• cv::v_uint32x4 and cv::v_int32x4: four 32-bit integer values (unsigned/signed) - int
• cv::v_uint64x2 and cv::v_int64x2: two 64-bit integer values (unsigned/signed) - int64
• cv::v_float32x4: four 32-bit floating point values (signed) - float
• cv::v_float64x2: two 64-bit floating point values (signed) - double

There are several types representing 256-bit registers.

• cv::v_uint8x32 and cv::v_int8x32: thirty two 8-bit integer values (unsigned/signed) - char
• cv::v_uint16x16 and cv::v_int16x16: sixteen 16-bit integer values (unsigned/signed) - short
• cv::v_uint32x8 and cv::v_int32x8: eight 32-bit integer values (unsigned/signed) - int
• cv::v_uint64x4 and cv::v_int64x4: four 64-bit integer values (unsigned/signed) - int64
• cv::v_float32x8: eight 32-bit floating point values (signed) - float
• cv::v_float64x4: four 64-bit floating point values (signed) - double

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.

• cv::v_uint8x64 and cv::v_int8x64: sixty four 8-bit integer values (unsigned/signed) - char
• cv::v_uint16x32 and cv::v_int16x32: thirty two 16-bit integer values (unsigned/signed) - short
• cv::v_uint32x16 and cv::v_int32x16: sixteen 32-bit integer values (unsigned/signed) - int
• cv::v_uint64x8 and cv::v_int64x8: eight 64-bit integer values (unsigned/signed) - int64
• cv::v_float32x16: sixteen 32-bit floating point values (signed) - float
• cv::v_float64x8: eight 64-bit floating point values (signed) - double

  Note

  512 bit registers at the moment implemented for AVX512 SIMD extension only, if you want to use this type directly, don't forget to check the CV_SIMD512 preprocessor definition.

  cv::v_float64x2 is not implemented in NEON variant, if you want to use this type, don't forget to check the CV_SIMD128_64F preprocessor definition.

  Load and store operations

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.

• Constructors: from memory,
• Other create methods: vx_setall_s8, vx_setall_u8, ..., vx_setzero_u8, vx_setzero_s8, ...
• Memory load operations: vx_load, vx_load_aligned, vx_load_low, vx_load_halves,
• Memory operations with expansion of values: vx_load_expand, vx_load_expand_q

Also there are fixed size register load/store operations.

For 128 bit registers

• Constructors: from memory, from two values, ...
• Other create methods: v_setall_s8, v_setall_u8, ..., v_setzero_u8, v_setzero_s8, ...
• Memory load operations: v_load, v_load_aligned, v_load_low, v_load_halves,
• Memory operations with expansion of values: v_load_expand, v_load_expand_q

For 256 bit registers(check CV_SIMD256 preprocessor definition)

• Constructors: from memory, from four values, ...
• Other create methods: v256_setall_s8, v256_setall_u8, ..., v256_setzero_u8, v256_setzero_s8, ...
• Memory load operations: v256_load, v256_load_aligned, v256_load_low, v256_load_halves,
• Memory operations with expansion of values: v256_load_expand, v256_load_expand_q

For 512 bit registers(check CV_SIMD512 preprocessor definition)

• Constructors: from memory, from eight values, ...
• Other create methods: v512_setall_s8, v512_setall_u8, ..., v512_setzero_u8, v512_setzero_s8, ...
• Memory load operations: v512_load, v512_load_aligned, v512_load_low, v512_load_halves,
• Memory operations with expansion of values: v512_load_expand, v512_load_expand_q

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.

• Interleave, deinterleave (2, 3 and 4 channels): v_load_deinterleave, v_store_interleave
• Expand: v_expand, v_expand_low, v_expand_high
• Pack: v_pack, v_pack_u, v_pack_b, v_rshr_pack, v_rshr_pack_u, v_pack_store, v_pack_u_store, v_rshr_pack_store, v_rshr_pack_u_store
• Recombine: v_zip, v_recombine, v_combine_low, v_combine_high
• Reverse: v_reverse
• Extract: v_extract

Arithmetic, bitwise and comparison operations

Element-wise binary and unary operations.

• Arithmetics: +, -, *, /, v_mul_expand
• Non-saturating arithmetics: v_add_wrap, v_sub_wrap
• Bitwise shifts: <<, >>, v_shl, v_shr
• Bitwise logic: &, |, ^, ~
• Comparison: >, >=, <, <=, ==, !=
• min/max: v_min, v_max

Reduce and mask

Most of these operations return only one value.

• Reduce: v_reduce_min, v_reduce_max, v_reduce_sum, v_popcount
• Mask: v_signmask, v_check_all, v_check_any, v_select

Other math

• Some frequent operations: v_sqrt, v_invsqrt, v_magnitude, v_sqr_magnitude
• Absolute values: v_abs, v_absdiff, v_absdiffs

Conversions

Different type conversions and casts:

• Rounding: v_round, v_floor, v_ceil, v_trunc,
• To float: v_cvt_f32, v_cvt_f64
• Reinterpret: v_reinterpret_as_u8, v_reinterpret_as_s8, ...

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.

inline

#include <opencv2/core/hal/intrin_cpp.hpp>

Load 256-bit length register contents from memory.

Parameters

ptr	pointer to memory block with data

Returns

register object

Note

Returned type will be detected from passed pointer type, for example uchar ==> cv::v_uint8x32, int ==> cv::v_int32x8, etc.

Check CV_SIMD256 preprocessor definition prior to use. Use vx_load version to get maximum available register length result

Alignment requirement: if CV_STRONG_ALIGNMENT=1 then passed pointer must be aligned (sizeof(lane type) should be enough). Do not cast pointer types without runtime check for pointer alignment (like uchar* => int*).

• 0xff/0xffff/etc: select element from a (fully compatible with bitwise-based operator)
