shz_memcpy32

SHZ_INLINE void* shz_memcpy32( void* SHZ_RESTRICT dst, const void* SHZ_RESTRICT src, size_t bytes) SHZ_NOEXCEPT;

Copies bytes from the src to the dst buffer in 32-byte chunks.

Parameters

Name	Type	Description
dst	void *SHZ_RESTRICT
src	const void *SHZ_RESTRICT
bytes	size_t

Returns

void *

Details

Transfers from 8-byte aligned buffer, src to 32-byte aligned buffer, dst, 32 bytes at a time. Returns the dst address.

Notes

• This is the quickest way to move 32-byte chunks of data around within memory, but the shz_sq_memcpy32() will be faster when writing through the cache to external memory.

Warnings

• dst must be 32-byte aligned, while src can be only 8-byte aligned. bytes must be a multiple of 32.
• src and dst buffers must not overlap.
