shz_sq_memcpy32_1

SHZ_INLINE void* shz_sq_memcpy32_1( void* SHZ_RESTRICT dst, const void* SHZ_RESTRICT src) SHZ_NOEXCEPT;

Copies src to dst in a single 32-byte transaction using the Store Queues.

Parameters

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

Returns

void *

Notes

• The Store Queues bypass the SH4's data-cache! They are typically used to transfer to external memory and are slower for memory-to-memory transactions.

Warnings

• dst must be at least 4-byte aligned, while src must be at least 8-byte aligned.

Naming and requirements

• sq_: Writes through the SH4 store queues (burst writes to memory or the PVR). (Naming and Suffixes)
