Cleans D-Cache

SCB_CleanDCache_by_Addr()

__STATIC_FORCEINLINE void SCB_CleanDCache_by_Addr	(	uint32_t *	addr,
		int32_t	dsize )

Cleans D-Cache for the given address D-Cache is cleaned starting from a 32 byte aligned address in 32 byte granularity. D-Cache memory blocks which are part of given address + given size are cleaned.

Parameters

[in]	addr	address
[in]	dsize	size of memory block (in number of bytes)

Cleans and Invalidates D-Cache

SCB_CleanInvalidateDCache_by_Addr()

__STATIC_FORCEINLINE void SCB_CleanInvalidateDCache_by_Addr	(	uint32_t *	addr,
		int32_t	dsize )

Cleans and invalidates D_Cache for the given address D-Cache is cleaned and invalidated starting from a 32 byte aligned address in 32 byte granularity. D-Cache memory blocks which are part of given address + given size are cleaned and invalidated.

Parameters

[in]	addr	address (aligned to 32-byte boundary)
[in]	dsize	size of memory block (in number of bytes)

Invalidates D-Cache

SCB_InvalidateDCache_by_Addr()

__STATIC_FORCEINLINE void SCB_InvalidateDCache_by_Addr	(	void *	addr,
		int32_t	dsize )

Invalidates D-Cache for the given address. D-Cache is invalidated starting from a 32 byte aligned address in 32 byte granularity. D-Cache memory blocks which are part of given address + given size are invalidated.

Parameters

[in]	addr	address
[in]	dsize	size of memory block (in number of bytes)

Invalidates I-Cache

SCB_InvalidateICache_by_Addr()

__STATIC_FORCEINLINE void SCB_InvalidateICache_by_Addr	(	void *	addr,
		int32_t	isize )

Invalidates I-Cache for the given address. I-Cache is invalidated starting from a 32 byte aligned address in 32 byte granularity. I-Cache memory blocks which are part of given address + given size are invalidated.

Parameters

[in]	addr	address
[in]	isize	size of memory block (in number of bytes)
