Function Documentation

◆ AdvancedProcessBlocks128_6x1_NEON()

template<typename F1 , typename F6 , typename W >
size_t AdvancedProcessBlocks128_6x1_NEON ( F1  func1,
F6  func6,
const W *  subKeys,
size_t  rounds,
const byte inBlocks,
const byte xorBlocks,
byte outBlocks,
size_t  length,
word32  flags 
)
inline

AdvancedProcessBlocks for 1 and 6 blocks.

Template Parameters
F1function to process 1 128-bit block
F6function to process 6 128-bit blocks
Wword type of the subkey table

AdvancedProcessBlocks128_6x1_NEON processes 6 and 2 NEON SIMD words at a time.

The subkey type is usually word32 or word64. F1 and F6 must use the same word type.

Definition at line 100 of file adv_simd.h.

◆ AdvancedProcessBlocks128_4x1_NEON()

template<typename F1 , typename F4 , typename W >
size_t AdvancedProcessBlocks128_4x1_NEON ( F1  func1,
F4  func4,
const W *  subKeys,
size_t  rounds,
const byte inBlocks,
const byte xorBlocks,
byte outBlocks,
size_t  length,
word32  flags 
)
inline

AdvancedProcessBlocks for 1 and 4 blocks.

Template Parameters
F1function to process 1 128-bit block
F4function to process 4 128-bit blocks
Wword type of the subkey table

AdvancedProcessBlocks128_4x1_NEON processes 4 and 1 NEON SIMD words at a time.

The subkey type is usually word32 or word64. V is the vector type and it is usually uint32x4_t or uint32x4_t. F1, F4, and W must use the same word and vector type.

Definition at line 254 of file adv_simd.h.

◆ AdvancedProcessBlocks128_6x2_NEON()

template<typename F2 , typename F6 , typename W >
size_t AdvancedProcessBlocks128_6x2_NEON ( F2  func2,
F6  func6,
const W *  subKeys,
size_t  rounds,
const byte inBlocks,
const byte xorBlocks,
byte outBlocks,
size_t  length,
word32  flags 
)
inline

AdvancedProcessBlocks for 2 and 6 blocks.

Template Parameters
F2function to process 2 128-bit blocks
F6function to process 6 128-bit blocks
Wword type of the subkey table

AdvancedProcessBlocks128_6x2_NEON processes 6 and 2 NEON SIMD words at a time. For a single block the template uses F2 with a zero block.

The subkey type is usually word32 or word64. F2 and F6 must use the same word type.

Definition at line 388 of file adv_simd.h.

F6function to process 6 128-bit blocks
Wword type of the subkey table

AdvancedProcessBlocks128_6x2_SSE processes 6 and 2 SSE SIMD words at a time. For a single block the template uses F2 with a zero block.

The subkey type is usually word32 or word64. F2 and F6 must use the same word type.
