Function Documentation

PMULL_00()

uint64x2_t PMULL_00 ( const uint64x2_t  a, const uint64x2_t  b  )

inline

Polynomial multiplication.

Parameters

a	the first term
b	the second term

Returns

vector product

PMULL_00() performs polynomial multiplication and presents the result like Intel's c = _mm_clmulepi64_si128(a, b, 0x00). The 0x00 indicates the low 64-bits of a and b are multiplied.

Note

An Intel XMM register is composed of 128-bits. The leftmost bit is MSB and numbered 127, while the rightmost bit is LSB and numbered 0.

Since

Crypto++ 8.0

Definition at line 34 of file arm_simd.h.

PMULL_01()

uint64x2_t PMULL_01 ( const uint64x2_t  a, const uint64x2_t  b  )

inline

Polynomial multiplication.

Parameters

a	the first term
b	the second term

Returns

vector product

PMULL_01 performs() polynomial multiplication and presents the result like Intel's c = _mm_clmulepi64_si128(a, b, 0x01). The 0x01 indicates the low 64-bits of a and high 64-bits of b are multiplied.

Note

An Intel XMM register is composed of 128-bits. The leftmost bit is MSB and numbered 127, while the rightmost bit is LSB and numbered 0.

Since

Crypto++ 8.0

Definition at line 64 of file arm_simd.h.

PMULL_10()

uint64x2_t PMULL_10 ( const uint64x2_t  a, const uint64x2_t  b  )

inline

Polynomial multiplication.

Parameters

a	the first term
b	the second term

Returns

vector product

PMULL_10() performs polynomial multiplication and presents the result like Intel's c = _mm_clmulepi64_si128(a, b, 0x10). The 0x10 indicates the high 64-bits of a and low 64-bits of b are multiplied.

Note

An Intel XMM register is composed of 128-bits. The leftmost bit is MSB and numbered 127, while the rightmost bit is LSB and numbered 0.

Since

Crypto++ 8.0

Definition at line 94 of file arm_simd.h.

PMULL_11()

uint64x2_t PMULL_11 ( const uint64x2_t  a, const uint64x2_t  b  )

inline

Polynomial multiplication.

Parameters

a	the first term
b	the second term

Returns

vector product

PMULL_11() performs polynomial multiplication and presents the result like Intel's c = _mm_clmulepi64_si128(a, b, 0x11). The 0x11 indicates the high 64-bits of a and b are multiplied.

Note

An Intel XMM register is composed of 128-bits. The leftmost bit is MSB and numbered 127, while the rightmost bit is LSB and numbered 0.

Since

Crypto++ 8.0

Definition at line 124 of file arm_simd.h.

VEXT_U8() [1/2]

uint64x2_t VEXT_U8 ( uint64x2_t  a, uint64x2_t  b, unsigned int  c  )

inline

Vector extraction.

Parameters

a	the first term
b	the second term
c	the byte count

Returns

vector

VEXT_U8() extracts the first c bytes of vector a and the remaining bytes in b.

Since

Crypto++ 8.0

Definition at line 150 of file arm_simd.h.

VEXT_U8() [2/2]

template<unsigned int C>

uint64x2_t VEXT_U8 ( uint64x2_t  a, uint64x2_t  b  )

inline

Vector extraction.

Template Parameters

C	the byte count

Parameters

a	the first term
b	the second term

Returns

vector

VEXT_U8() extracts the first C bytes of vector a and the remaining bytes in b.

Since

Crypto++ 8.0
